Luckily the debacle has been closed. Above two links that may interest you. The AVG scan detected a false positive... AVG 2012 installed on my PC says it's fine.
A more interesting thing is instead (I hope) that I'm going to try to update official MAMEUI source code and submit a test release to John IV to see if he's interested in upgrade his "baby". This will require really a lot of time so don't hold your breath.
