Hello All! I've been around a while but have not posted much. I've seen a lot of threads lately comparing various spy detectors, mostly Spy Sweeper and SpyCop with a few others here and there. I decided to do a test of my own and have taken screenshots to document my testing. The setup: 1 clean computer, running fresh install of Windows, nothing else. 28 keylogging and other monitoring type programs 13 adware programs (all I could get a hold of or I'd have more) Freshly downloaded free version of SpySweeper and SpyCop Trial First test - keyloggers Both detection programs claim to detect keyloggers. All 28 spy programs were placed on the test computer, and SpySweeper and SpyCop were let loose. The results: SpyCop found 26 of 28, though the trial said it skipped some files (kinda useless, really). SpySweeper found 9 of 28. Screenshots in attached picture. Second test - adware Computer was ghosted back to the original clean install of Windows to be clean once again, and the 13 adwares were installed. SpyCop says it isn't designed for adware in the startup screen. Let's see....the results: SpyCop found 8 of 13, SpySweeper found 13 of 13. Perfect score for SpySweeper!! I did notice that SpyCop and SpySweeper's names for the adwares were a little different, but I suppose it depends on where each company got the adware from. Screenshots in attached picture. Conclusion: Obviously these programs are not the same, and it appears that SpyCop is best for keyloggers (as they claim) and SpySweeper is best for adware. The results may also depend on the particular sample of spyware programs that are used. I think I'll purchase both to receive the maximum benefit of these products. Hope this helps someone! Look forward to me posting more in the future; college had taken a lot of my free time before.
