Moved to the correct section (VirusScan Enterprise) for better attention.
VirusScan Enterprise 8.0i is no longer supported I believe but the experts here will clarify that for you.
There is no removal tool for that. If it wont remove in the normal manner one uses to remove programs then you would have to follow this:
As Ex_Brit stated there is no removal tool for the vse 8.0, although many current corporate Av solutions may be able to remove the software during install (as later Mcafee versions do to them when installed) so this is worth testing.
The agent can be removed by triggering %path to install%\frminst.exe /forceuninstall /silent on the local machines via a script
Other than that its add remove programs or scripting the manual uninstall for VSE itself.
