My son's computer gets fake alerts about virus infections infiltrations and attacks, and requests that the user install "Antivirus System Pro". A google search on the net often sends us to www.porno.com. Operating system is Windows XP, SP2.

I was not able to start the already installed MBAM. Would uninstal and reinstall and it would start and I would run the quick scan and after two seconds of scanning, MBAM would disappear from the screen. Restarting would result in a message that the user is not authorized to use program, or windows doesnt specify a path for the program. Reinstalling and renaming MBAM, leads to the same result.

"Hijack This" wont start. AVG wont start.

I would appreciate any assistance in rescuing my son's computer.
