Installing VirusScan Software
38 McAfee VirusScan Anti-Virus Software
If you have no incompatible software on your system and your computer
runs Windows 95 or Windows 98, skip to Step 10 on page 40 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 Step 9 on page 39 to continue. Otherwise, continue
with Step 8.

8. 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.
NOTE: McAfee 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.
If your computer runs Windows NT Workstation v4.0 or Windows 2000
Professional, Setup next asks you which security mode you want to use
to run VirusScan software on your system (see Figure 2-6 on page 39).
