Help I got a computer virus

[bigairjay.]

I restarted my computer because it was making some annoying humming sound. When it came back on the display was huge, like the icons take up most of the page. I have to scroll over like half a page because it is so big. I tried changing the resolution but that didnt do anything at all. I don't know too much about computers so I come to you NS for help.

Any help is appriciated.

So I went to change the screen area of the screen because it was for the big size and i havea a small screen and then the display started to spin really fast. I restarted my computer and now its back to normal. This is soo fucked up.

Crack open the case and check to make sure all the fans are clean. Lil overheat might make that humming noise (clogged fan did on my laptop)

you probably don't have a virus. But go to www.grisoft.com and download AVG if you really want to check. It's a free antivirus program that I think beats Norton and McAfee.
