I tried ST a couple months back and checked its active protection. First I cleaned my system with Spy Sweeper, AVG AntiSpyware and CounterSpy. Then I shut them all down and ran ST for a week. I then shut it down and ran those three anti-spyware apps again. At that time I found nothing on my system, not even tracking cookies. And I was pretty impressed. Well taking that bit of info I allowed my Spy Sweeper license to expire and reoved ST from my system figuring I would just redownload it later. Which I did. Boy was that a mistake. I downloaded ST yesterday morning, ran it for several hours while I was on the internet visiting site, then ran a scan with AVG AS which found 21 tracking cookies. I thought that was a bit odd. So I ran all my spyware cleaning programs- besides AVG, I am now using SuperAntispyware as stand alone programs. Then making sure ST's active protection was enabled and up to date ran ST all of today for about 10 hours of internet time, visiting many sites. The count when I re-ran my AS programs to clean again- AVG, SuperAS (as well as ST) was as follows: SuperAntiSpyware 32- tracking cookies. AVG- 10 tracking cookie objects, 16 traces. ST- 10 tracking cookies (even with active protection on). Wow. Has crawler "updated" their ST program recently? Something is certainly strange about this.
