My computer keeps freezing when I attempt to scan it with my virus protection. I've tried it more then once and everytime I do. It stopps on: HKEY LOCAL MACHINE\SOFTWARE\Classes\http\Shell\open\command Only, I use firefox instead of Internet Explorer.. but when I do, just as of late, it has been freezing. Can the two be related in anyway. What can I do to fix the problem? Thanks in advance.
