as a matter of fact, it would also help to know which McAfee products you're using and which build/version. Grif is our resident ''McAfee Maniac'' and he usually see's these posts. (I think he has some form of radar going on. :D) It would help to have as much information as you can offer. The more the better. Have you scanned with anything? If so, what?
I do have some thoughts, but I would rather wait until someone more knowledgeable than I comes along.
3 weeks ago one of the computers (all are xp pcs) on my home network came down with this problem, now a second computer has it. This 2nd computer was running w/o virus protection, and i had to reload windows to get it unlocked. Internet explorer won't run, mcafee won't scan(!), can't even get system info or My Computer to open, so iexplore doesn't work either. (please don't tell me to go the the mcafee web site and run their online software - i can get on the internet, but not with IE, which Mcafee requires!) so far comp # 3 is ok. anybody know what this is or how to fix other than format HDs? i have the mcafee error message if that helps.
