Ultima's editor is just fine (and a nice piece of work, if I may say so; thanks mate). The fact that he's using UPX and AutoIt is what's causing those false positives. I've written a few free utilities myself and they are occasionally getting flagged as trojans and malware, even though I was using pure C++/Win32. I never bothered to contact the antivirus vendors, for the reasons Ultima mentioned. zploek, I know you're trying to help, but you really can't rely on antivirus products to be 100% correct. Sometimes you have to use your own judgement on their "findings". You'd be surprised how dumb their heuristics engines can be.
