Read a June '06 anti-spyware comparison on another forum this week that placed SpywareDoctor at the top of the performance heap! Spysweeper came in second and Counterspy was third. These 3 vie for positions at the top in many studies. I've tried Spywseeper before and uninstalled it because it was a resource hog. Haven't tried Counterspy, but just this week downloaded SpywareDoctor by PCTools. I'm very impressed with the easy GUI & features. It now has
rootkit detection capabilities and has 11 "on-guard" scanners/monitors. The comparitive testing was on some 24 antispyware packages. SpywareDoctor detected 96% and was able to remove around 81% of the nasties on the machines. This was quite a bit better than either Spysweeper or Counterspy on detecting and particularly on removal. Adaware SE came in sixth and Spybot was way down at place 14. WinDefender was at the
bottom of the list for both detection & removal. So far the SpywareDoctor uses around 48% CPU usage during an actual scan (so does Spybot) , but only while scanning the hosts file & registry. Then during the remainder of the scan Task Manager shows much lower usage.
I was running Spybot & Windows Defender until this week. I also use SpywareBlaster and Ewido & Adaware SE as weekly on-demand scanners. I have McAfee FW & Avast AV. No conflicts whatsover so far.
You might like taking a look at the new version of SpywareDoctor. Only downside I see is they have no user forum, only website FAQ & direct email contact for registered users. This is not freeware, however. Costs $29.95 for one year subscription. I believe there was a free trial period offered, but can't remember for how long.
