Checking What is Running

When checking your system to see what is running from time to time I find something I don't recognize. I will Google it. But sometime that doesn't work. Someone had posted a web site that worked great but I lost it. What site do you all use?

 

http://www.processlibrary.com/
http://exelib.com/
http://fileadvisor.bit9.com/services/search.aspx

I use the 1st, but i found these on my bookmarks. It's a jungle

 

Here's another goodie I use:

Thanks guys.
