given how this seems to happen with autohotkey regularly, i think if you are a ahk coder who distributes compiled exes, you have to accept that you are going to have to recompile your scripts each time a new version of autohotkey comes out, in order to overcome the previous release's signature being added to antivirus signatures. you'd think these anti-virus companies would learn by now.
speaking of which.. you know someone needs to make a page calling out the anti-virus programs based on which ones have the most false-positives. it's long overdue and i dont think the traditional antivirus review sites every test for this.
