Upon opening firefox a few days ago,the entire screen was different with no arrows, buttons, etc to move around so I hard closed it. The next time I tried to open firefox it would not respond. I did a system restore which did not work so I went back to an earlier restore point and now my computer states that it has found an error and needs to reboot which is is stuck in a loop doing over and over. At the bottem it states "critical system error found" and says to look into when the computer comes back up which it never does. What kind of program/virus was unleashed? I probably will have to wipe my hard drive and reinstall Windows and all the other programs I had. I am NOT a happy camper to say the least. What did you do, or what did some hacker of your system do? I am using a friend's computer as if the reinstallation does not work I will need to take it in to be repaired so I cannot take a picture of the blue screen that I get.
