I've run Spybot every week for almost a year, but about 6 weeks, it stopped finding any problems. Usually I had a couple dozen, but now there is nothing. I have not changed much else on my Dell Inspiron 1420, but I have tried reinstalling and updating Spybot several times, neither of which helped. I am worried that my computer is just filling up with stuff that Spybot is now missing, any ideas?
