Version 1.6. Win XP, dual-core proc and 2GB ram and very few programs installed. Have used spybot on all my computer for years and had no problems, now on my laptop its so slow its unuseable. Everything else works fine and the program will finish if I had a day to leave the computer on. I have removed and reinstalled the program, it will update fine, but just runs super slow while every other program is fast. Can't figure out why?
