Yeah, my AV quarantines files rather than deleting so I can tell it not to... also Micro$oft's form for submitting false positives (ie telling them their AV screwed up) is currently completely broken so without the dev trying to get in contact with them or hacking their file it won't get fixed... bad for everyone involved but M$, big surprise there *sigh* Monopolies get you bad software, big surprise.
Sometimes you can tell your AV to quaratine instead, or not to check certain directories... that could help but sometimes they also check at time of execution which means that they'll try and stop it when the file is run when you start the game and delete it then... at least this means you have a copy of the file you can copy back but it doesn't help running the game.
