I'm running spybot 1.4. I usually update my detections once a week and I did so yesterday afternoon. When I ran spybot last evening it took about 6 hours to get to where it was about 75% done. I was forced to stop it. Until yesterday it used to take about 10 minutes to finish. I rebooted, tried a few more runs and the same thing happened. I assume the program got corrupted. I tried running two other spyware detection and removal programs and they had no problems. In fact they detected only two inconsequential spyware objects. I have decided to download and reinstall spybot 1.4. My question is this - should I remove my old version first using my XP (home edition) add/remove programs or will the 1.4 program I am installing overwrite the previous version making the removal of the previously installed version unnecessary?
