Donna created a great post comparing the major spyware active protectors and testing them with Hotbar
The results are very interesting, please see

Thanks, Haroldo.
Very interesting reading.

Reaffirms my confidence in Spywareguard. Catch it before it downloads, got to love it.
I've been using it for over 3 yrs., and it has saved my behind on several occasions.

Kind of disappointing, about Spybot's Teatimer and SDHelper, though.

I would have like to have seen the results based on more than one sample, though, since testing against one known malware hardly justifies any real conclusion about the application's overall usefulness.It points out the hardly novel fact that anti-spyware applications differ, but as a reminder, it is interesting.
