Super Stall,
If you removed the virus with the patches while running your affected Operating System, you are fine. (If you had pulled the hard drive out of the computer and used it as a slave on another computer, it would not have removed the virus properly.)
I am currently running 4 instances svchost.exe, two system, one local service, and one network service. The size of the memory usage will change. That is normal.
If you see any other problems with your computer, please report back. Otherwise, just monitor it.
Take Care,
Richard
