First he needs to dump AdAware.... it doesn't work. and there is a lot of spyware that when it attacks, the first thing it does is disables AdAware and Spybot. Spysweeper is updated frequently, and is currently good for some 180THOUSAND threats. CC shouldn't have to worry about "reinstall/partition" of anything.
After he runs the apps I suggested, he will have loads of room and resources again. I only have a 40 gig HD but I am only using 28% of the capacity of the HD. Every time I run Window Washer, it clears a couple of gigs of space, and I do maintenance weekly. When CC does what I recommended, hes gonna freak when he sees all the crap that is wiped from the "hidded" windoze cache files, and all traces of spy ware and tracking cookies, all of the hidden internet cache files, and then there is the internet history.....

My daughters laptop had 147 instances of spyware right out of the box.

One other thing... if your running AOL, dump it!!! AOL has an incredible amount of ITS OWN built in spyware and worms. When I deleted their pre-installed software, if took me 6 months to get rid of ALL of it, and I am still not sure about that.
