I have used and loved Unlocker in the past. (Helps delete files that are in use by running programs.)
The site that hosted it was http://ccollomb.free.fr/
It seems to be dead now. Anyone know a reputable source where I can get this tool now?

FileHippo and Softpedia have the latest version.
You may also be interested in LockHunter, another freeware tool which works similarly:

The new website is here http://www.emptyloop.com/unlocker/
Ignore poor software like lockhunter and fileassassin, just use Unlocker.
+1 to what John T said
Also, if you're just having trouble with deleting individual files, Malwarebytes' FileASSASSIN is the most reliable software IMO.
