Removing program files
Use these tasks to remove the VirusScan Enterprise program files.
NOTE: McAfee strongly recommends that you restart your computer after you remove files and
before you reinstall the software.
When you remove files using Setup or the command line, some files or stopped services might
not be removed. For example, if you remove VirusScan Enterprise while the McAfee Task
Manager or the McShield services are stopped, these services are not removed. Restarting after
removing files ensures that all files and services are removed before reinstalling the software.
