A little while ago when i oppened internet explorer multiple windows of it oppened up (like hundreds), i got out of them all and then i went to my winamp playing , the same thing happened, i went to turn of my pc but it logged me out , when i logged back in to turn off my computer it logged me out again, the screen colours started turning brown then black, so i turned the computer off by pressing the button.
Would this be a virus? or someone hacking my computer?
i had msn messenger and overnet running at the time
