File Check on NIS 2009

Is there a way to do a complete file check, to make sure the software hasn't been compromised in any way?

 

Reason I'm asking right now:  Im building out my laptop currently, and the password protection I entered for NIS didn't work for me later on in the day.  Now, of course there's no way at all I could have entered the password incorrectly on both lines or forgetting the password I used, naturally someone hacking me and changing my NIS password is much more reasonable (particularly when I wasn't browsing at the time)..  :-) 

 

Still, I'd be curious if there was a way to check the install, or if NIS has self-protection methods in place to be sure the software itself hasn't been tampered with.  Not referring to settings of course, but the software itself.
