Nod32 Bombing out with VNC Scan Enterprise Manager

We have been using a great remote administration program named VNCscan (http://www.vncscan.com) for about 4 years and recently we started getting errors from imon.dll when doing a scan for VNC on the network.

I finally found a post on their forums that told me to upgrade to the newest version of NOD32. Sure enough, when I did, the problem went away.

Any idea what was causing this? I've pasted the URL to the forum thread for anyone else that runs into this problem.
