A few months ago, my computer started slowing way down and sometimes I would get up in the mornign and my computer was already logged in - did it all by itself.

So after some searching, I downloaded a program calld Ad-aware 6. It was free and did a scan of my PC for "spyware". Found something like 80 files and several forms of spyware that got secretly downloaded and was sending info about me to who knows.

I've got all that stuff remove and run Ad-aware every couple of weeks and once in a while if still finds something suspicious.
