Is there an ap for finding/deleting corrupt files on OS X 10.7?

Question

I seem to have a corrupt file(s) which cause my MacBook Pro to freeze inexplicably (and randomly) upon start-up. I've been told that this is a symptom of having a corrupt file.
Is there an an for finding/deleting corrupt files on OS X 10.7?
I'm pretty much bound to my computer and simply don't have the time to go through it manually.
Thank you.

This is an old post and I am not the person who posted the original query, but I ran your terminal diagnostic and am hoping you are still attending to this forum. I have a mid 2011 macbook Air 11", 256 GB SSD, 1.8 GHz Intel Core i7, 4 GB  1333 MHz DDR3, Mac OS X v. 10.7.5 Lion. I have had various problems in my user homefolder for a while. I have gone through quite a few other troubleshooting and fixing steps, the most extensive following a posting here "Step by Step to fix your mac" by ds store in the Apple forums. These steps helped a lot. I did remove some 3rd party software as part of this process.
My computer is running well in general now, but one thing that has been a recurring problem is problems with move/cut-paste. I researched this online and ACL's being present where they're not supposed to be seems to be an issue. I have used terminal commands to remove ACL's, used Onyx to repair user permissions, rebooted with command-r to reset password screen and reset user permissions. They all help, but then a some point later on the problem recurs. When I run repair disk permissions with either disk utility or onyx I always get this message:
Repairing permissions for “maggieairHD”
Warning: SUID file “System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent” has been modified and will not be repaired.
ACL found but not expected on “Users”
Repaired “Users”
Permissions repair complete
This ALWAYS comes up, even if I run it immediately after running it and haven't done anything else on the computer in between.
I created another user and did not have the same problems I was having at the time with some programs, although I haven't used it that much to be able to really compare. The home folder permissions repair in Onyx comes out the same in that user, though.
Here are my results from your diagnostic terminal commands:

Maggies-MacBook-Air:~ maggieair$ osascript -e 'tell application "System Events" to get the name of every login item'
NoSleep, iTunesHelper, Caffeine, Dropbox
Maggies-MacBook-Air:~ maggieair$
I have removed NoSleep, Caffeine, itunesHelper and Dropbox from login items before and didn't notice any difference, so I put them back. Some of these I know I don't want, like rim/blackberry, adobe AIR. Skype has never worked consistently on this computer. I don't use most of these Services, and I know I had trouble with some that were not compatible with Lion before. I am not using Parallels much now, have been thinking about taking it off as it uses a chunk of my SSD. But I don't feel confident about getting rid of .frameworks etc safely.
I am glad to remove anything I don't use if I know how to do it safely. I am willing to remove anything I do use if it's necessary, but obviously would prefer to find a way to keep things that I find helpful.
I appreciate any suggestions!
