Just found this one yesterday, very nice full time replacement for taskmgr.
Gotta love that for each svchost.exe process it lists what services are associated. Makes a great companion to MS' own command line "SC" for managing services.

"Process explorer" traces process inheritance and can find processes by dll name if you can identify them. That's a good way to detect fishy programs. The problem a lot of people slap on resident programs like Symantec and Norton antivirus and what not, and it becomes a bit harder to tell which ones are real or not. It's a lot easier if you kept track of your clean systems and what is considered the norm. Not so easy when you are trying to help on someone else's computer.
