OK, I've scanned the exe online using a virus/maleware scan software which is connected to 67 different antivirus engines.
It is interesting that 9 of 67 antivirus softwares think that there are different viruses/malewares in the uccnc.exe file.
Now the funny part is that I now tested a backup copy of an older UCCNC version written onto CD.
That CD was resting in the self around 1.5 years now and why I moved it now is to test, because that version was earlier scanned using the same engine and no viruses no malewares nothing was found.
And voila, now scanning the exact same old file now gives the same 9 positive out of 67 virus/maleware reports.
So, the issue is definately in some virus engines recent updates, because that file was not changed, it is written on a permanent CD disk and was previously scanned years ago and then it gave negative only results.
The bug therefor is in those antivirus definitions and not in the uccnc.exe file.
