[NTG-context] Warning Trojan.Agent.EZ in texmfstart

Hi, I know this has been asked before, only that I did not experience the problem ... Since months I use Bitdefender antivirus software. I never experienced any problem running texmfstart. However since three days Bitdefender thinks, that the executable texmfstart from 27-07- 2005 contains a Trojan. I checked the size of texmfstart.exe. I got an older version which is 580kB the one which gives problems has 596kB. Copying the older version into the tex-tree works fine and Bitdefender does not complain. First question is: which is the actual version and size of texmfstart.exe? Provided that there is nothing wrong with texmfstart.exe with the size of 596kB should I contact the Bitdefender developpers? Kind regards Willi
