Let me give you a little insight.
Roughly 15% of Windows users are using AVG and 15% Norton/Symantec and unfortunately both of them pick this app as a "downloader" threat. It might be more as I have not personally tested with other brands. While you may claim this as a false positive, there is a good reason why these security researchers consider this app as a threat. It has a behavior that seemingly resemble that of a virus, does it not? I think it's time you guys start working on the solution to get around this "false positive" issue instead of telling 30% (maybe even more) of your values customers to switch off their antivirus software and leave their computers vulnerable to attacks.
By the way, it's amazing how you guys push out these trainers and editors so quickly after a game release or any updates. Keep up the good work!
Disabling/Uninstalling an AV is a troubleshooting step, not a permanent solution as indicated in the troubleshooting guide that nobody reads. It is there to determine if the AV is the point of cause and if it is, then the user needs to take additional steps to configure or do whatever in order to remedy the problem. As this is the most common ailment with "OMFG TRAINER NOT WORKING", it is one most cited when users go straight to reporting a defect without any kind of information nor reading the troubleshooting guide.
In short, please read the troubleshooting guide. Topic Locked.
