I am not fussed on McAfee at all!
The security I use is listed below.
Try booting into Safe Mode, as per instructions below, and doing a scan with
McAfee.
If if does not work, uninstall it, and install Avast Anti-virus, and repeat
scan.

Avast Anti-Virus is Vista compatible (32bit and 64bit Versions), FREE,
auto-updating, and a low resources user of your computer.
And, only have 1(one) Anti-Virus installed / running on your computer at any
one time..
Conflicts may occur if you have more than 1(one).

Spybot Search & Destroy 1.5.2 is a very good, FREE Anti-Spyware Program.
Download, install, update, and immunize your System with it.
Then SCAN with it.

SpywareBlaster 4.0 is a non-intrusive, FREE Anti-Spyware Program that runs
in the background.
Update it once a fortnight, and let it do its work in the background!
If you happen to find a problem that you can’t uninstall / delete, reboot
the computer, and go into Safe Mode.
To get into Safe mode, tap F8 right at Power On/ Startup, and use UP and
DOWN arrow keys to get to Safe Mode, then hit ENTER.
RESCAN your computer with Avast and Spybot S & D while in Safe Mode.
