I thought it was experienced with
Spywareblasters immunization too, not just Spybot SD. I guess maybe it was both.

Wasn't aware that MS had a fix for that problem.
I used to like Spybot, but since updates to the program are practically non existent, or way to few and far between for me, and only malware definitions are updated, even those are kind of slow to come in, I never use it anymore. Plus IMO, it's ugliness and awkwardness make Avast's current GUI look like a beauty queen. Of course, that has no relevance on the performance of the program. But hey, just some of my own opinions. Not to be confused with advice.
