Any further checking would be beyond the scope of my technical ability. Any idea of the time and cost involved to have a person competent in this area look it over?

Really depends on the amount of data on your site; I had to do a cleanup of a really nasty hack on a client site where I had to work with his webhost directly to clean up the mess and it took about 12 hours to accomplish (though his issues extended far beyond his forum just being hacked).

My general baseline minimum as far as a quote would go is ~3 hours @ $120/hr; which would include comparing ubb files for any "new" files, looking at all files newer than a couple of weeks, going through every line of code on your site and looking at post requests, etc.

Hi guys !
I have made an account on this website !
I appreciate the choice of the topic chosen also appreciate the discussion because it is really informative for me !
A user reported the above message generated by their corporate security system. I am running 7.5.3.

The security system is ESET NOD32 V4 Business Edition.

We're going to need your forum URL if you want us to take a look at it.

It looks like this reply was made to my posting from 5 months ago. But I'm sure it was directed at the poster below mine.

In any case, in order to possibly help the new poster here's what I had to do ...

• upgrade ubbthreads to 7.5.6p2 to pick up the security patch
  
• reload the OS on my server
