No it's not that simple. That's how it worked in the past on the old trainers. I would just perform an exception to the folder with the trainers.
The few new trainers perform a dropper action into a tmp folder. It's that dropper/file in the tmp folder that triggers the warning. There is no way to exclude that. I can not exclude a whole tmp folder (for a good security reason). AND, if I exclude just that one file, then it will get detected again once the cheat is ran again and a new file is created.
All my downloaded files go into a flagged (any AV) folder I named "Downloads" on my "M" drive with a link on my desktop, thus easy to 7Zip a CH trainer and install it in my "Games" folder.
The trainer executes fine...but then the dropper gets picked up. Here is an example from Assain Creed 4 Black flag AC4e

the problem is anti virus software, which (to try and remain relevant) are flagging ANYTHING suspicious more and more to try and prevent people from getting virus.
most fresh virus are NOT caught immediately and are put into the virus signature files once they are identified. the rest of them are caught by literally random heuristic shotgun approach..
there is no good solution to this, other than to ***** at the antivirus software makers, who likely will ignore you. we dont plan on changing our policy of trying to prevent piracy of our trainers...
