Disabling processes on enable on-access scanning
Disabling processes on enable during system startup reduces your system startup time.
If the on-access scanning process on enable feature is configured, all programs or executables
are scanned when they are started. When you start your system some programs or executables
start automatically. These executables might start prior to starting mcshield.exe. If the process
on enable feature is configured and the mcshield.exe starts after these other executables the
on-access scanner will scan each of the previously running executables in the order they started.
This can slow your system and increase your system start up time.
To change the processes on enable setting using ePolicy Orchestrator, access the VirusScan
Enterprise 8.8.0, On-Access General Policies, and click the General tab. Confirm Processes
on enable is not selected.
The following ePolicy Orchestrator 4.5 shows processes on enable deselected.
