F-Secure Email and Server Security manual scan causes system to hang

F-Secure Email and Server Security manual scan causes system to hang - F-Secure Community

After initialing a manual scan, the server/system experiences noticeable degradation in performance causing the server/system to hang.

Scanning large archives may cause the CPU usage to increase by 50% - 100%.

To overcome this issue, set an archive nesting limit for manual scanning:

Start Windows Registry Editor (regedit.exe).
Set the following registry on the server:
- If you have a 32-bit system: [HKEY_LOCAL_MACHINE\SOFTWARE\Data Fellows\F-Secure\GKH2] "MaxArchiveNesting"=dword:00000001 (1)
- If you have a 64-bit system: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Data Fellows\F-Secure\GKH2]"MaxArchiveNesting"=dword:00000001 (1)
Restart the FSGKHS service for the change to take effect.
