I keep noticing that the available amount keeps shrinking 2-6gigs a day. I haven't downloaded anything new. I've cleaned out recycle bins and disk cleanup. Temps and downloaded folders too. I ran cc cleaner.
I've installed 3 virus protection software, norton, adaware, spybot search and destroy, no viruses.
It's weird, I'll be sitting at my desk and look back a few hours and 2 gigs are gone.
