Welcome to the community. 
Trainers will sometimes trigger what is called a false positive in antivirus programs no matter what platform you get that trainer from. The reason this happens is purely as a precaution due to the way that trainers work - which is by injecting code into memory addresses that the game is using, in your PC’s RAM.
It’s also sometimes triggered because WeMod uses state of the art encryption that makes it impossible for WeMod trainers to be ripped by leeches and re-uploaded with shady junk in them. The antivirus cannot identify this encryption (which is a good thing, means it’s still unbreakable) so it flags it as a precaution.
The false positives are nothing new, it has been an issue for decades with trainer use, long before WeMod even existed (trainers came into existence in the 1980s).
As a community and marketing manager in the game development and blockchain industry, I wouldn’t spend my time as a moderator at WeMod if I didn’t believe in the product or if the product was shady.
In my time here at WeMod, there have been no infections given to any of the millions of active users over the years. There have been people who don’t understand what false positives are or how trainers work making enquiries, sure, but nothing actually shady being passed on.
