Important: Some malware camouflages itself as symlcsvc.exe, particularly when located in the C:\Windows or C:\Windows\System32 folder. Therefore, you should check the symlcsvc.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 symlcsvc. 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 doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
