For a week now I think my computer has a virus yet avg and clamwin free anti virus don't pick anything up when scanning.Adaware picks up this thing with a tac rating of 7 that is always there no matter how many times I scan but i'v had that even before the problem. Which brings me to my problem after the computer is on for an hour or so everything starts working . I click firefox or IE or a exe application like a game or aim and nothing opens up not even cntrl alt delete. Now lets say firefox was already open or IE then I can continue to browse them but if I close out I can't open anything back unless I reboot. Any ideas on how I can get rid of this bug? And is it a virus or a reoccurring computer glitch like a BSOD? Can someone give me some advice that doesn't have to do with system restoring [ can't it was turned off ] and reformatting the computer?
