Overview
When scanning a remote machine using a profile that includes scanning of Microsoft Security patches, it increases CPU utilization.
Environment
GFI LanGuard
Root Cause
- When using a profile that scans for missing Microsoft Security updates, the GFI LanGuard server or agent copies the wsusscn2.cab file to a numbered sub-folder of the directory C:\Windows\patches\ onto the remote computer used by the Microsoft Windows Update agent.
- Scanning of this file by one or more 3rd party antivirus products can cause high CPU usage.
