I think this isn't uncommon with RPG Maker VX ACE installers, but there aren't any real issues. If you can't (or don't want to) tell the antivirus to exclude the file, I'll upload a zipped version instead, that one shouldn't freak out the AV. I am probably not going to do this for all updates, however, as it's a bit of a waste of time (I'll do it for the 1.0 release, though). Expect the link to appear in the game's page in a few minutes.
