I trust that this is XP SP3? If not read here for some helpful hints on achieving that: http://community.mcafee.com/thread/2007 also read here regarding what happens to an unpatched XP: http://community.mcafee.com/docs/DOC-1315
I split this from the original thread which I have now locked as it was obviously dead.
Try the remedy I posted for someone else in the same situation here: http://community.mcafee.com/thread/25331
Very helpful document. How do I update the stinger program? I tried to download again but the link in the DOC is broken. 404 error is noted. Thanks,
It appears that part of the wrbsite is down.
Try this instead. Download the free version of this software. Install it, update it and then run. Let it remove anything it finds and reboot when asked to.
