Personally I rather not uninstall my AV just to play a game. I would exclude my games folder from being scan but some trainers seems to be using tmp files location which I won't exclude.
Indeed. The trainers that are created by the guy who makes the editors, are actually a .net trainer that was wrapped in pwizard loader, so the actual trainer is unpacked to the temp folder to protect distribution of trainers without identification.
It's possible to send the trainers to kaspersky so they would identify it as false positive so you can play them after the next kaspersky definition update.
But that's a long way.
I'm using KIS 2014 and also got no problems with the trainers (so far). Notable Mention: I'm using the application in manual mode.
But CH knows best and you guys r all professionals happy holidays cheers!
