Is Winlog.exe a Legit File?

The genuine winlog.exe is a personal security file.

Winlog.exe steals personal information, and secretly conducts crypto mining for cybercriminals.

The malicious winlog.exe is installed into your PC on the ProgramData folder and blends itself with other files. It is then launched through Winlog.bat, a file containing the malware’s information for conducting the malicious activity.

Can Winlog.exe Be a Virus?

As noted above, some malware entities also use the file executable name winlog.exe. Examples of identified malware with that name are Suspicious.SillyFDC or Backdoor.Trojan. Therefore, you need to always monitor the winlog.exe process on your PC to check if it is a malware.

Once executed, the malicious winlog.exe program creates multiple entries on the Task Manager, under different names such as Cmd.exe or timeout.exe. It tries to mask itself to avoid detection. However, many users may not know where or how to spot these processes.

Should Winlog.exe Be Removed?

Best Practices to Resolve Winlog.exe Virus

  • Use Disk Cleanup (cleanmgr) to get rid of temporary files that take up space, which Windows doesn’t need anymore.
  • Use System File Checker (sfc/scannow) utility to examine your Windows files for any errors and restore the damaged files caused by some installations, viruses, or tuning tools that may impersonate or damage your Windows system files.
  • Uninstall programs on the Windows programs and features to remove the programs that you no longer need or unnecessary programs.
  • Checkg AutoStart programs (msconfig) using the Microsoft System Configuration (msc) utility to resolve problems when Windows starts up. You can disable Startup Programs and Services to eliminate possible causes of windows AutoStart problems.
  • Enable Windows’ Automatic Update to ensure that essential Windows updates are always installed on your PC automatically.

Note: If the problem is serious, instead of reinstalling Windows, you can repair it (for Windows 8 and higher) by executing the DISM.exe /Online/Cleanup-image/Restorehealth command. This command checks your computer’s health and allows you to repair the OS without losing your data.
