Windows XPpro SP2 on Dimension 8400, 3.2MHz HT P4 1GB RAM. Task Manager is reporting 3 instances of Rundll32.exe running under my user name at the same time; 3 instances of SVCHost.exe running under System, 2 more running under Network and 1 running under Local Service. No 2 instances of the same process are using the same amount of memory.
PF usage is 281M/2458M

I did cold boot and same thing. Is this normal?

McAfee, Ad-aware, Spybot all up-to-date and reporting nothing suspicious. PC otherwise seems to be working ok.

Any ideas?
Thanks!
