Used to have somewhat the same, like some other Dr. Web users on this forum. Adding to PWizard, Dr. Web blocks 0x90's trainers, more specifically, AppData\Local\Temp\~Mnn133.tmp file. One could try finding and whitelisting it, has worked for me.
Besides, it seems like the latest trainer doesn't work due to the latest game hotfix in Steam (freezes the game for me, at least).
