Yea you can do that. But I just intalled a new antivirus program last night so I don't wanna lose it. lol
Did the problem start after you installed the new virus program? if so that could be the cause of your problem, it you purchased a physical copy of it i would roll it back a day or two and reinstall the virus program, you might have had something else open (browser, Napster, limewire) running or bad transfer , just make sure nothing is open or running when you reinstall, if it was a digital download you should still have access to the download and reinstall it from where it's stored, and remember to have nothing else open, hope that helps
