This window lets you configure the file protection for the profiles in your organization.
To access this window, go to Antivirus > Files tab > Advanced settings.
You can choose to scan all files when they are created or modified regardless of their extension.
This option does not improve your protection, actually it may negatively affect PC performance, but increases immediacy in the sense that it scans absolutely all files at the time when they are created or modified.
The alternative is to scan only files with certain extensions. To do that, you can exclude specific extensions, files and folders from the scans.
Use the relevant button (Add, Delete and Clear) to select the list of items (Extensions, Folders, Files) to exclude from scans.
When you have finished, click OK to save the changes.
