How to Know If Malware Is Completely Removed from PC?

Given how advanced technology is today, cybercriminals employ malware to infect users with their malicious programs, which have a terrible and damaging impact on the end user who has been infected.

This is done by utilizing their knowledge of coding and programming. Every computer user has long struggled with malware, and despite antivirus software’s claims that it has been eliminated, we will always have concerns that it may still be lurking in the background of our computer system.

How to Know If Malware Is Completely Removed from PC

We cannot rest easy knowing that they could still be inside the computer, aware of what we are doing, and could launch an attack at any time.

That is why it is necessary to thoroughly inspect the system once again in order to determine whether a virus has been totally removed from the computer. To be sure a virus has been successfully eliminated, follow these steps:

Double check by scanning the system with up-to-date antivirus software: The initial step is to do a thorough scan of the system using up-to-date antivirus software. Any lingering infections on the system will be easier to find thanks to this. If you have already done a scan before, try doing so with a different antivirus since they have different threat and signature databases to detect malware in the system.

Check for suspicious processes: Look for any suspicious or unknown processes in the list of active processes on the system. Malware frequently starts background activities that are simple to miss. It is crucial to remember that discovering such processes can be challenging for normal users; look for processes using a lot of hardware.

Look for modified system files: Malware frequently modifies or replaces system files, therefore it’s crucial to make sure that all of them are in their original configuration.

Check the registry: The Windows operating system’s crucial registry is a frequent target for malware. Check to see whether the registry hasn’t been harmed or altered by the infection. Even though it could be challenging, manual verification is required to ensure malware is completely removed. Look through these directories where malware is most likely to be hidden:

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion

Keep an eye on network activity: Keep an eye on network traffic to spot any odd activities. This can assist in locating any persistent malware that is in contact with outside command and control servers.

Here is a step-by-step guide on how to confirm that all malware on the device has been totally eliminated for those who are not very tech-savvy.

Step 2: Use System File Checker and DISM Cleanup

DISM Cleanup and the command-line tool Windows System file checker can be used to verify the stability of all significant system files. Additionally, it checks to determine whether any system files are missing or corrupted by comparing them to their original versions.

9 Once the scan is complete, it will report that the operation was successful and corrupted files and entries are resolved.
