Alright probably wasn't a good idea to post that while having AVAST on, so here's my problem.
My friend decided to get me to download this game called like Call to Arms or something, it's been in A LOT of ads all over the internet. Well every time I launched it gave me an error (not sure what it was though), so I uninstalled it seeing as there was really no reason for it. I then noticed that CSS WOULDN'T launch and wow was HORRIBLY slow.
I came into firefox and noticed, it too was slow. I tried EVERYTHING I could thing of, from running a virus scan to deffraging, which defrag only took me like 10 seconds so I think somethings up there. Disc cleaner could only find like 11 MB of stuff to clean

. Plus I got rid of like 3 gigs of programs.
Now my computer is lagging, I don't think my HD is reading itself correctly and is giving me the wrong amount of gigs it has left.
Now I plan on reformating my HD which I can't do since my SD card is only 2 gigs and I have like 20 gigs of pictures, programs, and docs that I need saved to something. Plus my dad won't lend me an external HD from work even though I REALLY need one.
So I'm stuck and have NOOOOO idea what to do.
