I run McAfee, Spybot and Adware on my XP. When I downloaded the SP2 it screwed up so many programs and was an overall pain. I removed it and will never try it again.
Good luck to you.
I did remove it, but still couldn't access the management console. It is back in, and I am waiting for MS to respond to My report. Things are running OK, but sooner or later I will need to defrag.
I also run AVG, and Spybot, as well as BitDefender and Adaware. Also, Spyware Blaster. Only problem I've had lately is Wootbot showing up from somewhere, but it gets caught. I am tired of messing around, will just stay on MSs tail until I get an answer, if You are persistent it will happen.
