What is a Trojan virus?
Trojan viruses are computer threats that are known for disguising under a legitimate program or process name for they do not get detected by the user.
The Trojan virus imitates trusted system processes and popular programs that many people use to carry out its harmful activities in the background of the computer without anybody being aware of them, much like the Greeks would disguise a horse as a gift before it was later discovered to have several warriors inside it.
This malware can be acquired via email attachments from unknown senders as well as from downloading files from suspicious torrenting platforms and websites that offer cracked software.
Such computer viruses should not be left alone in the system as they may cause data breaches and financial losses knowing that a Trojan can have many different malicious operations on the computer it infects.
What does the Trojan virus do?
Trojan viruses can steal the data of the user whether it is login details that are stored in the system files of the computer or saved account details cached in the web browser.
Dealing with such a virus can be harmful since it can lurk among the computer files and scan them for something with value that can be stolen by the cybercriminals who developed them.
In addition to that, they can also implement other types of malware that can not only steal data from the computer but use the infected computer as a botnet or use it to mine cryptocurrency which will be directed to the malware actor’s wallet.
It can also lock the computer’s sensitive data, making them useless. If the files are particularly vital, like old recollections and highly valued work-related information, this can be a disaster of an event.

The harm that Trojan viruses bring to the PC
The risks that Trojan viruses may impose on the computer are very high and can be completely damaging depending on the payload and types of Trojan injected into the computer.
In rare cases, all of the computer systems are shut down and will be locked by ransomware that can keep you from using your computer by making you not get past the boot screen.
On the other hand, your computer may get downloaded with a miner virus and when this happens, you may suddenly see that your system is getting slower and that the computer is overheating.
Not to mention the effects that the Trojan virus has on your personal and financial accounts. It can hunt for important data which can be then sent to the cybercriminals.
They can have access to all of your accounts if you have previously entered or logged them in your browser because they can steal the cache and access it from there.
Another case is where it can track your keystrokes while hiding in the background without the user noticing it.
When this is the case, whenever you logged in to certain accounts or enter your credit card details, cybercriminals will be able to see whatever you were typing on your computer.
It can also be viewed as a privacy violation because everyone you communicate with or email can be monitored by cybercriminals. In addition to that, Trojan viruses may also contain spying software.
This malware can access the webcam and audio device of the computer and record users’ activities, which hackers can then use against them to demand money.
Types of Trojan viruses
Depending on the type of Trojan virus that was installed in the computer, all the malicious behaviors can range from a minor security concern to a serious one that can ruin the computer and everything inside of it. Below are the types of Trojan viruses known to be installed on the computer.
A rootkit is a sort of trojan that hides its presence on a computer while giving cybercriminals privileged, root-level access to your system. Simply defined, it is a nasty form of malware that can seriously harm the operation of your PC and pose a security risk to your personal information.
Ransomware is a type of malicious threat that encrypts every file in the user’s computer making it useless and unable to be opened. It appends a certain extension and utilizes a highly complex algorithm so simply renaming the file extension back to normal would not solve the problem.
They would leave a ransom note on the computer alongside a crypto address to which you would have to send money if you want your files back. We highly recommend against paying the ransom price since there is no guarantee that your files will be decrypted back by the ones who did it in the first place.
Information-stealing malware, commonly referred to as stealer malware, is a type of malicious software intended to gather data from the victims’ computers and send it to the hackers who created it.
They target and collect information explicitly, including login credentials, bank account information, credit card numbers, and other crucial data that can be exploited.
A miner virus is used to mine cryptocurrencies and is secretly installed on a system without the user’s consent while using a system process name to avoid the user being suspicious about the miner software.
Attackers utilize the machines they infected to mine certain cryptocurrencies such as Bitcoin, Ethereum, and Monero because such crypto mining activities require a lot of hardware power.
The malicious actor will then receive the cryptocurrency they mined from the user’s computer and it will then be sent to their wallets.
Trojans and other harmful software can be downloaded and launched by downloaders. This type of threat is used to download additional malware to the user’s computer which can pose more security risk to the system.
Downloaders are typically employed as a gate to install as much malware as the cybercriminals want on the infected computer. The downloader malware is frequently installed via suspicious websites that may contain malware downloads.
How to detect a Trojan virus from the computer
Trojan viruses hide in the computer so detecting it may be difficult for some users who may not be knowledgeable about using their computer. Here are some of the ways how to detect malicious threats from the computer.
Monitor Task Manager for intensive CPU usage
Finding out if a Trojan is present on the computer can be done by checking the Task Manager for processes that are using a lot of hardware.
It may be hogging computer resources to mine cryptocurrency if you notice processes intended to be idle or known to not use as much hardware are doing the opposite.
Some of the most common names that cybercriminals name their Trojan viruses are Svchost.exe, Csrss.exe, System.exe, and others that may seem to be too important to be suspicious of.
To avoid deleting important system files, you should look at where the suspicious process is located in the computer, if it is not in the Windows system directory, then it is malware and you should delete it.
Open Control Panel and look for programs you did not install
Control Panel is a Windows program that can be used to check all of the installed programs in the computer alongside their file size and which developer created the said application.
Knowing if malware is present in the computer will be easy by checking for applications that you did not install and do not recognize to be something that should be in the computer.
Another thing is by looking at the developers of the application, certain Trojan viruses will have unrecognized developers and some will not have one presented on the details of the application.
The version of the program can also show if a certain program is a Trojan in disguise because newly created programs will have the 1.0 version shown.
Looking at the icon of the program is another indication, some programs that are posing as malware will not have an icon and will use the default Windows program logo.
Use an antivirus program to detect Trojans automatically
The most straightforward technique to find out if a Trojan infection is hiding in the computer is to use an antivirus tool.
Although it can conceal itself from the user by using legitimate application names, antivirus products are likely to detect it since they do not rely on the program name to identify whether a program is harmful.
Antivirus programs use complex signatures to determine if a program or process is malicious so if you cannot find the Trojan using the previous methods given above, scanning with an antivirus will surely detect the malware.
With that being said, presented below is a step-by-step instructions you can follow to remove the Trojan virus from the computer.
How to Remove Trojan Virus From Computer
The methods provided below will assist you in removing the harmful trojan virus from your system.
Removing malware from the system should be thorough and carefully executed; therefore, please follow every step provided.
We made the instructions below easy to understand so non-tech-savvy users can still remove the computer threat without needing help from tech support or a computer technician.
Step 1: Uninstall suspicious programs from the computer
To remove the harmful trojan from your computer, we have provided two ways to do so: one is through normal uninstallation, and if that does not work, we also provide an advanced uninstall method to make sure it will be removed without issues.
Remove programs you do not recognize via Control Panel
The most common way to remove the trojan virus from your computer is to uninstall the program through the Control Panel. You may view all of your installed apps as well as the developer’s name in the list of applications.
1. From the Windows search bar at the bottom of your screen, search for Control Panel and click the result that matches the same application.
2. You will see different options, such as System and Security, as well as User Accounts. But what you want to click is the Uninstall a program under the Programs section. Depending on your Windows version, hovering over the uninstall section will be relatively the same.
3. Now that you are on the Programs and Features page, it will show you all the installed programs. There will be filters you may want to use, such as viewing them in lists with details such as the publisher, version number, and when they were installed.4. Right-click the suspected program and click Uninstall to get rid of it (We will be using Adaware as an example). It will then proceed to remove the application, or you will be presented with an uninstaller that will guide you to remove it; either way, it will be removed.There is a chance that the program may not be uninstalled successfully, and when that happens, it is important to use the power of an uninstaller program such as Revo Uninstaller.
It is widely known to be enough to remove malicious programs that are evading uninstallation. If you encounter such an issue when proceeding to uninstall the app, you may utilize the uninstaller to do the job for you.
Remove Trojan virus via Revo Uninstaller
For computer users who are not sure of what to do. You may resort to using Revo Uninstaller since it is much more effective and easy to use. Revo Uninstaller is a handy tool for Windows users.
This uninstaller not only removes programs from the computer but also deletes their changes from the Windows Registry, Host File, etc. Following the steps below will guide you on how to install and use Revo Uninstaller to get rid of the Trojan virus.
1. Click the button below to proceed with installing Revo Uninstaller on your computer since we have made an in-depth guide on how to use it on the following page. On the other hand, you can also head over to Revouninstaller.com and download it from there.
2. After the setup file (revosetup.exe) has finished downloading, run the installation wizard, read the license agreement, and click agree to proceed to the next step of the installation. Follow the procedure and wait until the installation of the software is complete.
3. Once the software has launched, find the suspected Trojan and double-click the program to uninstall it.
4. Click on the Continue button and follow the procedure to start uninstalling the suspected trojan virus. It is also advised to make sure that a System Restore Point is made before the uninstallation, just in case. (We will be using Firefox as a demonstration.)
5. You will be prompted to choose a scanning mode. From the three options available, select Advanced mode, then click Scan.6. A window will pop up and show all of the leftovers and changes made by the uninstalled program. Click the Select All button and hit Delete to remove the leftovers found in the Windows Registry.
Once the window closes, you have successfully removed the Trojan virus from your computer system.
Step 2: Delete the Trojan virus manually
There is a chance that the Trojan virus may not be an installed Windows program but rather a single executable file that is hiding in the computer. If this is the case, then you can remove it by locating the source of the file and deleting it from there.
Please follow the instructions below to find and delete the malware manually from the computer.
1. When the trojan virus is causing your computer to overheat, launch task manager by simultaneously pressing the Ctrl, shift, and Esc buttons. Another option is via the Run program by pressing the Windows key and R, then typing taskmgr.2. Check the processes that are running on your computer right now to discover how much hardware they are using once Task Manager has opened. Once you have located it, right-click on it and select Open file location.
3. Make that the file location does not originate from a Windows system directory, such as the C:Windows\System32, after the File Explorer has opened up while highlighting the suspected file, since you may risk unintentionally deleting a system file. If the software is not from a crucial directory, delete it by selecting it with the right-click menu.
If the file refuses to be deleted because the process is running as well as if certain programs are preventing it from being uninstalled, simply enter Windows Safe Mode and delete it from there.
Before doing so, please remember the directory where the virus is located because Safe Mode prevents non-essential files from running on the computer.
To boot into Safe Mode, first, open the system configuration by pressing Windows Key + R button then type “msconfig.exe“.
Once the System Configuration window appears, click Boot next to General then check the Safe Boot from Boot options. Below that, tick the Network option to allow internet within the Safe Mode then click Apply, once everything is done and the computer should be restarted into safe mode.
After booting into the said mode, go to the directory where the suspected virus is located and delete it. It should be able to be deleted now that the configurations preventing it from being removed are blocked in Safe Mode.
Step 3: Scan with powerful malware removal software
The Trojan virus may be hard to delete and for users who are not knowledgeable about their technology, it is best to utilize a program dedicated to removing such threats from the computer.
For these virus threats, we recommend running a full system malware scan with Malwarebytes Anti-Malware. This program is widely known and recognized by security experts when it comes to removing viruses from the system.
Remove Trojan virus with Malwarebytes Anti-Malware
We have also been using this software on our systems ever since, and it has always been successful in detecting viruses. It has blocked many known computer threats as shown from our tests with the software, and we assure you that it can remove the trojan as well as other malware hiding on your computer.
Not to mention, it is free to use and does not come at any cost to remove the viruses it finds on your computer.
To use Malwarebytes and remove malicious threats from the computer, follow the steps below:
1. Download Malwarebytes by clicking the button below, as we have made an additional and in-depth tutorial on how to use it. Otherwise, you may go to their official website via Malwarebytes.com (Avoid misspelling as it may lead to scams).
2. Visit their download section and start a Free Download to begin installing the software on your computer.3. Once the Malwarebytes setup file (MBsetup.exe) has finished downloading, open the executable file in File Explorer, then right-click the setup and select run as administrator to give the highest system authority and make sure Malwarebytes is installed correctly.4. Make sure to carefully follow the installation setup wizard’s instructions and provide the relevant information it requires. You will be prompted with questions such as Personal or Business Use, Email Address, and others.5. From the application’s home screen, go to the scan tab and begin running a system scan. This will scan the whole computer, including memory, startup items, the registry, and the file system. This is done so that not only the Trojan but also other malware hiding in the system will be detected.6. Since it can take a while, you should either relax and wait for it to finish or find something else to do. The length of the scan depends on the size of the files you have and the hardware capabilities of your computer. Here are some ways to make scanning faster.
7. Once the scan is finished, Malwarebytes will show the malicious viruses and threats it found on your PC. The Trojan virus will show up on the detection results, and it will show up in a threat name such as TrojanCrypt.Generic, and many more.8. Select all the detected files from the report and click the quarantine button to remove the malicious items from the computer into the protected safe quarantine zone of the anti-malware program so that they would not affect and do malicious actions to the PC again.9. After placing the virus files in the program’s quarantine, it may prompt you to restart the computer to finalize the full system scan procedure. Please restart your computer if prompted, as it is essential. After the restart, Malwarebytes will open and display a message that the scan was complete.
Note: Don’t forget to delete the quarantined files afterward.
Simply quarantining the malware files is not enough to make sure they are completely removed. This is a very common misconception: once you click the quarantine button, it is all good and gone.
But, while its effects and harmful activities are halted, the malware is still in the system, only placed in the anti-malware program’s quarantine folders. To completely remove it from the computer, go to Detection History from the home screen, select all Quarantined items, and click Delete.
You have successfully removed the harmful Trojan virus as well as other hidden threats on your computer. Rest assured they would not resurface again since Malwarebytes offers a premium trial for 14 days, so you could take advantage of it for free and prevent malware from infecting your system.
While the detection and removal of malware is free for Malwarebytes, the premium versions include real-time protection that ensures your computer is safe all the time. Although we encourage you to use the premium trial, you are free to purchase the full version if you find it useful.
The program is an anti-malware that removes harmful threats like trojan horses, worms, stealers, miners, keyloggers, and many other forms of malware and computer viruses.
We suggest Malwarebytes if you are looking for a removal tool and as a second opinion scanner, but if you want full-fledged antivirus software, we believe that the built-in Windows Defender is sufficient for computer security, or if you want something with a more sophisticated system and better protection: Kaspersky Free.
If you choose to uninstall Malwarebytes, you may suddenly see that Windows Defender Real-Time Protection is turned off. This is a common issue that users may face when uninstalling the software. To fix this issue, you may refer to this article.
Alternative: Kaspersky Free Antivirus
After removing the Trojan virus and other malicious threats, you may want to install antivirus software to protect your system against malware.
More importantly, running an additional scan with a different program’s threat database will alert you to hidden Trojan viruses and rootkits that were not removed from the prior scan with Malwarebytes.Kaspersky is a widely known antivirus software that has been on the market for as long as the field of cybersecurity has existed. It is acclaimed by professionals in the field and is one of the most effective antivirus programs available. With its advanced internet security protection, it can also remove additional malware from the computer.
What is the difference between anti-malware and antivirus? Anti-Malware software is designed to specifically remove malware and its variants. In addition, it employs heuristic-based detection by picking up harmful code from files.
On the other hand, an antivirus uses signature-based detection, which examines data for attacks to protect users from dangerous viruses, including keyloggers, loaders, worms, trojans, and others.
Malwarebytes and Kaspersky are identical, but Kaspersky is a better overall program since Malwarebytes’ main purpose is to remove malware, but Kaspersky has been known for comprehensive computer security protection ever since.
Based on our experience removing malware, when two different programs are used to scan, various threats are identified by one software but not by the other. Given that their threat databases differ from each other, it might be able to capture harmful viruses, rootkits, and trojans that Malwarebytes has missed.
Please be aware that if you decide to use Kaspersky, you should first uninstall Malwarebytes because having both security programs installed will cause a conflict. If you choose to do so, please remove Malwarebytes first, as it is essential to do so before we get started.
1. Click the button below to start downloading Kaspersky Antivirus on your computer. On the following page, we have provided clear details on how to install it on the computer. On the other hand, you may go to their official website by searching for the software on your web browser or typing Kaspersky.com (Beware of misspellings since cybercriminals typically use these as exploits to redirect users to malicious webpages).
2. Go to the download page for Kaspersky Free Antivirus. Before clicking download, you will be prompted to choose your continent and where your country is located. This is very important, and you should not choose a different country because you will be met with a “Not supported in your region” message during installation.3. Once you click download, a setup file (startup.exe) will be downloaded on the computer. After it has finished downloading, open its file location, right-click the executable file, and then select Run as administrator. This will ensure that Kaspersky’s installation will be smooth and will not result in certain errors.4. The Kaspersky installation wizard will launch, and you can then proceed to install Kaspersky Free by following the setup instructions. If a UAC prompt appears, simply accept it and proceed with the installation.5. Please be patient while Kaspersky is being installed on your computer. The speed and length of the installation process will depend on your computer’s specifications. Kaspersky also mentioned that sluggishness or dark displays during the installation of their program are normal and should not be worried about.
6. To use the antivirus program, you must first create an account on the sign-in page that appears after the antivirus application has been successfully installed on the computer. If you’re looking for the sign-up button, simply enter your email exactly as it appears; if you don’t already have an account, one will be created for you.7. Kaspersky will ask you to decide which plan to use. It will be either the Standard version or Kaspersky Plus. In this case, the standard version is all you need for now. If you want to try the premium version of Kaspersky, you may opt for Kaspersky Plus to try the features for free. You do not have to add a payment method to get started, and after the trial ends, you will be downgraded to the Standard version unless you pay for it.8. You will be asked if you want to install additional applications, namely Kaspersky Password Manager and a VPN. Feel free to opt for a program you might want to use; otherwise, install both, or choose not to if you do not need them.9. Kaspersky will ask you to scan for viruses in the background. Simply choose not to do so because we will be doing a full system scan later; however, doing a scan now will only initiate a quick scan. However, if you want to be safe, you can run the background scan now and proceed with a full system scan after.10. Once the antivirus application has opened, go to the security tab and click the choose a scan button. You will be presented with several different scans; go for the full system scan to ensure full computer security. Always remember to update the database because this will ensure that Kaspersky can detect newly discovered threats and exploits.11. A full system scan will take a long time to finish since it will look into all the files on the computer, including the registry, memory, startup applications, and many more. The scanning time will depend on how many files there are on the computer and how big the files are. Additionally, the computer’s hardware and specs will also play into how long the scan will take.
12. After the full system scan is finished, it may detect remnants of the Trojan as well as other malware hiding in the computer, showing its location along with a detection name (HEUR:Trojan.Multi.Powedon, HEUR:Trojan.Win32.Generic, etc.) given to it. Go ahead and proceed to disinfect and restart the computer.13. The Advanced Disinfection process will then start, and depending on the amount of RAM the computer has, it could take some time. It will then request a computer restart to complete the operation.Your computer will now have finished the entire system scan after restarting. By doing this, you can be sure that the Trojan virus and other forms of malware and viruses have been wiped from your computer.
You shouldn’t be concerned if the scan turned up no instances of malware or viruses, which indicates that there isn’t any malware on your computer. If two independent programs declare your computer safe, then that’s probably the case.
For a better and safer web browsing experience, we’ve provided a few security measures and advice below that will safeguard your browser and computer from harmful threats like worms, malware, trojans, keyloggers, stealers, and other kinds of computer viruses that will harm user data.
Protective measures for better overall security
Removing the Trojan and other malware from the computer is one thing; keeping it secure for the future and a long period is a different thing and will require certain things to make sure you are secured, especially if you do not know most of the ins and outs of the device you are using.
Cybercriminals are always stepping up their game to make sure they infect users and extract data and money from them.
We encourage you to take the actions listed below to ensure complete security before leaving this page because we strongly promote web security and having a secure online presence.
Safeguard your data and privacy online by using a VPN application
VPNs, also known as virtual private networks, guarantee your safety and complete anonymity while you browse the internet.
In contrast to a firewall, which monitors and blocks potentially harmful connections in the network, A VPN hides the user’s connection via a tunnel so that it would appear to third parties as a different IP address and location.
This ensures that your data won’t be leaked because the program hides it. Be aware that visiting infected websites may cause your IP address and location to be disclosed; however, if you use a VPN, this will prevent your true IP address from being revealed to malware actors.
If you already had Kaspersky installed from the previous step, you had the choice to install its integrated Virtual Private Network, which is a good tool that we also advise.
However, if you decide against doing so and instead download a VPN-only program to cloak your web browsing activity, Mullvad, and AirVPN are excellent choices for fast connections and better privacy.
Since user privacy is the main focus of a virtual private network program, Mullvad VPN excels at putting users’ privacy first. You do not need to enter your email address while registering to download their application because they maintain anonymous accounts.
If you wanted to hide or didn’t want your credit card information to be disclosed, they also accept Bitcoin payments. According to their website, they support a free internet that is devoid of surveillance and censorship.
They have also been announcing new server locations to guarantee users a fast connection anytime they want to connect to various areas throughout the world.
AirVPN seeks to provide users with access to the real internet, in contrast to Mullvad, which promises to offer users a free internet. Along with masking your IP, they also don’t monitor or log any user data, which is good.
You can use it for a long time without worrying about being disconnected because they don’t impose a traffic or time limit when connecting to their network. In addition, there are infinite, cost-free server changes with physically fast servers in many different nations.
Additionally, when registering for their program, you are not required to enter your email address. They also offer strong encryption and Perfect Forward Secrecy to ensure that it is difficult to determine the user’s connection.
Use a firewall to prevent cyber attacks
A security firewall is required for every internet connection that is made. It is an essential tool that enhances security and stops online attacks.
Through a security mechanism, it controls incoming and outgoing network connections on your system and network and filters the undesirable ones. Consider it a further barrier against malicious assaults and zero-day exploits.
You don’t need to do anything if you installed Kaspersky in the previous step because the program we installed earlier comes with a built-in firewall that is turned on by default.
On the other hand, if you prefer a standalone, fully functional firewall utility application that is exclusively focused on securing the network, we recommend these top two firewall solutions for personal computers: Comodo and ZoneAlarm.
Comodo Personal Firewall
Comodo Firewall is a well-known software program for securing your network and computer. It is a sophisticated tool with a wide range of features.
It is simple to use and doesn’t require complicated configuration to set up. It also functions by being aware of your computer usage habits to avoid interfering with your work.
Additionally, it claims to offer the highest levels of protection against both inbound and outbound threats. It secures the ports on your computer from hackers and prevents rogue software from sending your sensitive data over the internet.
ZoneAlarm Free Firewall
You can also opt for ZoneAlarm Free Firewall as your first line of defense between your device and the internet. The program safeguards your network and blocks any dangers, and you can use the free version of it without paying anything.
It provides a robust two-way protection solution that guards against spyware from disclosing your data online while also hiding your PC from nefarious hackers.
With its cutting-edge anti-bot protection, it also protects your computer from automated cyberattacks in real-time.
Additionally, it protects your computer against spam, dubious websites, and many others. Lastly, it provides real-time defense against automated cyberattacks with its cutting-edge anti-bot security.
While this may appear to be typical advice, we recommend users not visit illegal streaming or torrenting websites and more importantly, download anything from them because doing so may result in the installation of malware and viruses.
Because these websites are illegal, they are unable to make a profit from legitimate advertising. As a result, they host questionable advertisements from unidentified marketers that want to publicize their contents, which are most likely dangerous codes being propagated by cyber criminals.
Always make sure that your device is protected against sneaky exploits and stealthy cyberattacks. While taking precautions and avoiding dubious websites are crucial, having a solid line of defense is essential to ensuring the security of your network and data.
