If Setup finds incompatible software, it will display a wizard panel that
gives you the option to remove the conflicting software.
If you have no incompatible software on your system and your computer
runs Windows 95 or Windows 98, skip to Step 9 to continue with the
installation. If you have no incompatible software and your system runs
Windows NT Workstation v4.0 or Windows 2000 Professional, skip to

7. Select the checkbox shown, then click Next>. Setup will start the
uninstallation utility that the conflicting software normally uses, and
allow it to remove the software. The uninstallation utility might tell you
that you need to restart your computer to completely remove the other
software. You do not need to do so to continue with your VirusScan
installation—so long as the other software is not active, Setup can
continue without conflicts.
Š NOTE: McAfee VirusScan Software strongly recommends that you
remove incompatible software. Because most anti-virus software
operates at a very low level within your system, two anti-virus
programs that compete for access to the same files or that perform
critical operations can make your system very unstable.
