VirusScan control panel files
As the initial process for all VirusScan components, the VirusScan management 
service does not depend on other VirusScan components. It does depend on some 
Windows system components to run, however.
This table lists VirusScan control panel files and points to where you can find them.
Temporary files
The VirusScan control panel and its related files use these files as “memory maps” to 
store configuration options copied from the Windows registry when the program runs. 
These files start out with a standard file size and minimal data, and grow or shrink as 
necessary to accommodate configuration data.
