My computer, a six years old dinosaur, is living its last days. Soon to be replaced by a new slick, mean machine, it is making a valiant effort to keep helping me with my work. Recently, it is even slower than ever, and I get more blue screens than usual. I also noticed than whenever I run Ad-aware, it finds Win32.Trojan.Downloader which reinstalles itself upon reboot. Any help would be highly appreciated.
