The Windows installer has a virus! What the ****?
First of all, relax — it’s not a virus. It’s just a false positive and it’s actually not that uncommon. Prey uses AutoHotkey (AHK) scripts for some of the stuff in Windows (i.e. cron.exe and the Lock module), and it so happens that some antivirus softwares don’t like AHK too much. You can add an exception on your antivirus or you can also let the files be quarantined, however in that case some stuff may not work. Please let us know if you get a false positive so we can get in contact with the antivirus vendor and get those files whitelisted.
