Exceptions for Safetica services

If you are getting suspicious operations alerts from your antivirus regarding Safetica services such as STCservice.exe, STContentservice.exe, STEventservice.exe, or STAservice.exe, you can set them as allowed.

Exceptions for files and folders

Set these exceptions in your antivirus software:

For all systems:
