McAfee calls this one "Patched User32". Read carefully the "Characteristics" and "Removal" sections at http://vil.nai.com/vil/content/v_144583.htm and follow the instructions there.
If your McAfee program cannot remove this, I doubt whether GetSusp will be fully effective against it since a lot of the damage is in the registry, but it will at least identify any suspect files and so might be worth running. You should certainly try the Stinger tool, which is downloadable from HERE.
If the infection is still present follow the removal instructions HERE.
Have you tried a scan in safe mode?

There is a Doc with some other suggested programs you can try the stingers and getsusp the latter will find any files that are suspicious and send them to Mcafee. If you have added your email addy to the preferences Mcafee will update you re the files and any new dat to fix them.
