In my opinion Spybot is next to worthless.
I had a keylogger, a couple of Trojans, and a few other
spyware apps on my system. I'd run a full scan with
Spybot, and it found nothing. I downloaded and installed
thr trial version of Giant AntiSpyware a few days before
Microsoft bought them out. It found a ton of things that
Spybot simply overlooked. Most of these itmes had been
on my system for a long time, as some of them were from a
few years back when I was still going to Wright State
University in Dayton, Ohio.
Not to mention the fact that if you want to change your
IE settings, you have to launch Spybot, shutdown the
Immunization feature, shutdown Spybot, make the cahnages
to the Internet Options in IE, launch Spybot, restart the
Immunization feature, and shutdown Spybot. I can't even
begin to say how stupid the operation of this feature of
Spybot is. MSAS, and almost all other antispyware apps
simply make certain that no one other than the user make
those changes.
