AntiVirus Free freezes at 5% and see virus ref "..Protected item."

Hello Doug,

A virus message or "An application is requesting access to a Protected item. (Plus some strange characters - different characters each time it starts) " appears when I start AVG Antivirus Free on my old XP laptop. I saw a post that recommended to do the repair routine.  Did that but after next restart I got the same situation - freezes at 5% and virus message appears again.  Any thoughts?
