This tool is a must use for us before any Joomla upgrades, afterwards to ensure that the upgrade went smoothly, and periodically as a check to make sure that nothing has been unintentionally modified on our server.
There are known hacks out there which modify specific core Joomla files in order to send login credentials to 'bad' people by email, to insert spam in output, or other nefarious things. The Version Verification Tool will help you to know as soon as possible if your site may have been unknowingly modified.

I tried admin tools (akeeba)but just got 500 errors when I tried to run the file checker.
I installed this component, ran it and found the infected file in seconds. It was actually in a very obvious place but 1 line at the top where I didn't notice it.
Thankyou, this is a life saver!
I checked my files - found on a site that one file wasn't the 'official' version and updated it.
It would be fantastic if it could also update any files that weren't official versions, but it's still great!
Thanks for the feedback. I use the "Update Manager for Joomla!" (available on the JED) to update my files directly. I would love to add the ability to show the difference in files as well as allow auto updating going forward. We also set up the component to allow comparing files for any Joomla! extensions, which I think will be very useful. We just haven't had time to improve on it...but we will try to as soon as possible.
Thanks again for the feedback!
