All this bloatware MS is adding to their products annoys me.

I have just recently cleaned a SP2 box (without that last IE patch) infected by a hackdoor variant. Several antivirus and spyware scanners could not do it so manual intervention was required.

Do you think they can do much better with a spyware scanner?. Sure, it will reduce malware more but remember that the malware writer wants their program undetected too and a spyware scanner by Microsoft sure isnt going to make them give up.
