I didn't do any background check on this site, which does appear to resemble a familiar site that provides information for checking legitimate/illegitamate system and application files.
But my response to you is "why bother"?
When I am investigating my StartUp files, or checking on a specific possibly suspicious file.... I use Google, which will link references to several "process checking sites" like www.liutilities.com, www.neuber.com, www.symantec.com, or castlecops.com. I find it an advantage to receive more than one recommendation to confirm information I would use in making a decision.
If I were to use a single source, I like either of these guides:
