after module installation, my antivirus said that this is trojan, is ok??

If I say "yes, it is okay" and you just take it as granted, I'd gladly slap you on the back of your head with a shovel. You should not trust anyone just like that.

1. There are no viruses(at least when I've used it last time).
2. The found danger has probably come from the euristics module, which does not detect specific viruses, found in a virus database, but rather assume danger, based on what the file can do. Since even small things like downloading files off the internet can be considered dangerous, antiviruses are never shy of reporting it as a danger.
3. The file reported is probably the automatic installation script. You can avoid using the file you deem "infected" by just removing it and not using it. Just do things manually.

It is a trojan horse

Details, please.

The last time I've checked, in this thread( https://psteamcommunity.yuanyoumao.com/workshop/filedetails/discussion/1678408548/3371531159450557044/ ) it was known to be a mere heuristics warning.
PDM:Trojan.Win32.Generic.nblk - is a response from a heuristics module.

Ok then don't have fun in gmod vr if you don't want to. Your choice

Ok

So, can I REALLY know if it's safe ? I mean, losing my computer to a vr mod would be kinda stupid. So, anyone let me know if it's safe or it has a virus

DLL file's code is available at the dev's github, so you can always analyze what is happening inside, and even build it on your own.
Addon's LUA scripts can be opened using Notepad and read.
Autoinstaller script can also be opened using Notepad and read.

If you cannot make sense of that information, then sorry, there is literally no way you can "REALLY" know if it is safe, except blind trust/gamble.

It's NOT a trojan. The module is okay to download, running it through virus total brought up nothing. If you STILL think it's a trojan, go play Roblox VR then.
