After having the 707 on my system for quite some time, last night my antivirus program detected a Trojan in the 707 TCE program :-/ Shortly after I turned on my pc, the McAfee antivirus indicated a "Generic dx!CZ" file in the TCE and deleted the TCE executable. No, I don't download and install questionable programs. As far as I know, my pc has been clean as a whistle. And, yes, I purchased this software LONG ago from here. I can still access the aircraft in FS9 without issues. just can't use the TCE for repaints now. :(
