I tried installing another game in the folder that COM3D2 was in and the entire folder was deleted beyond recovery lol, didn't even go through the recycle bin, just gone instantly along with a few other games that were in the folder. I experimented with that game's installer and it actually permanently deletes the folder you install it in. It's not even a virus, the installer is just incredibly buggy.
I think I'll wait a few years before re-installing COM3D2 cuz I'm still in the bargaining stage of this loss.
And I don't feel like waiting a week to download the torrent and spending months getting back to where I was in the game.
Anyway, don't be like me and make sure you install COM3D2 in its own folder to avoid situations like this lol, be safe out there.
(I'm not looking for advice, it's been weeks already and the folder is completely gone, just warning my fellow gamers.)
