Important: Some malware also uses the file name patch.exe, for example Win32:Malware-gen or Win32:NetBus-AO [Trj] (detected by Avast), and Artemis!1E29FFAA4225 or NetBus.svr (detected by McAfee). Therefore, you should check the patch.exe process on your PC to see if it is a threat. We recommend Security Task Manager for verifying your computer's security.

A clean and tidy computer is the key requirement for avoiding problems with patch. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.
Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
To help you analyze the patch.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
