CCAPP.EXE
SVEHOST is a system process I think msmsgs.exe looks like windows messenger (The ancient MSN that comes with windows) Just go to run, type in msconfig and disable it so you'll never have to worry about it again, and ditch the Norton, get something like AVG and turn it 100% off and fire it up ONLY to scan, obviously when not gaming, This is what I do, Works well, I haven't had a virus in at least 5 months.

I also found another one of those memory eatting things. svchost.exe Please tell me why I have so many things that eat my memory.
