Well, I think I just figured something out. If you don't pay for Trayit it gets the Tray it download from an external source. So the one external source that I downloaded contained a virus.... I should have scanned it. You will only get the virus if you download Trayit for free and if the thing pops up saying open or save and it says MadHck on it. MadHck does contain virus.
Btw the virus basically ate up half my files.
..try to system restore...Last time i got a virus i system restored and it goes back to a set time *before virus*. Should work if you have a set restore point.
