I found out recently that the new Spy Sweeper 5.0 is taking a real long time for scans for some reason. When I first upgraded to 5.0 the scans took about 8 minutes, which was significantly better than 4.5. Let me note here that 5.0 has on the Options screen a slider at the bottom that you can use to increase CPU usage and scanning speed. Unfortunately it's not all that obvious. (I run scans at maximum speed.) I also don't like the scanning/sweeping options to be on the Options screen; I think they belong on the Sweep screen. Recently the same scans have been taking 45 minutes. Ridiculous. I do not include scanning for rootkits, as the instructions on SS 5.0 say it can double scanning time. I also run Spyware Doctor 3.8 (just now 4.0), and there have been some interactions with SS that I have noted on another thread and solved with Bubba's wise assistance. So I tried exiting Spyware Doctor before running the Spy Sweeper scan. Sure enough, the scan time was back to 8 minutes. I then reopened Spyware Docor and scanned again. It was very slow once more. Exactly what the deal is here I don't know, but the best advice seems to be to disable Spyware Doctor if you have it, do the Spy Sweeper scan, and then restart Spyware Doctor. The two applications do not seem to interact very much otherwise. I also have Spybot, Windows Defender, and NIS running with active protection, but there does not seem to be a problem with them and Spy Sweeper that I am aware of.
