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 malicious extension but also other trojan viruses hiding in the system can 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 Key Pro extension will also show up on the detection results, and it will be given a threat name such as Adware.ChromeLoader.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.

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 enough 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.
Protective measures for better overall security
Removing trojan viruses and malware from the device is one thing; keeping it secure for the future and for 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.
Utilize a firewall to prevent data from being sent to cybercriminals
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.
If you want a 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.
Safeguard your data by using a VPN application
VPNs, also known as virtual private networks, guarantee your safety and complete anonymity while you browse the internet.
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.
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 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 servers. 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.
The steps for locating harmful browser extensions on the browser and thoroughly removing them from the PC have now been covered.
