h**p://www.sysinternals.com/ntw2k/freeware/procexp.shtml. Not sure if that is the link mentioned above?

I agree with Seph in regards to checking for a virus/trojan, but more likely spyware. Adaware is good for that.
Only other thing I could suggest is running msconfig and clearing out what you dont need at startup.
