Welcome to the community. 
Every now and again, trainers will trigger what’s called a “false positive” in antivirus programs. The only reason this happens is because of the way trainers work - which is by injecting code into memory addresses in your PC’s RAM that a game is running on.
WeMod also uses state-of-the-art encryption to prevent its trainers being “stolen” by leeches, or ripped and re-uploaded with shady junk in them. Antiviruses cannot identify this encryption (which is a good thing!) so trainers sometimes get a false positive for that reason too.
You can find this information by using the search feature in the top-right of the community. For example: My antivirus marked WeMod as a Trojan
We do not and never will have a trainer for Verdun. It is a server-side game, which are impossible to modify with trainers.
Trainers only work on client-sided games - aka games running on your PC - not from a server hundreds/thousands of miles away from you). Because, as said, trainers inject code into RAM memory addresses, which is not possible if the game isn’t running on your PC.
