I'm afraid it could be an antivirus software thinking it's harmful, I've had some users report things like that before. The software is not malicious in any way but somehow the engine has gotten itself on the list of a few antiviruses and reporting it as false positive to every single one is a fair bit of work. Are you using just windows defender or something else?

HURAY I CAN PLAY NOW AND NOW I CAN'T DELETE IT XD, either way the game was a blast, the animation, shooting, models and sound effects are amazing, the mission was great but there's only 3 different one though, there's also a lack of map, I like how that once one operator died it dead forever much like the game darkest dungeon but can improve the operator through completing mission(sometimes I don't realize that my guys got overpower XD), love the rotatable crosshair might want to use that as reference, only thing lacking is more content and balancing the difficulty like maybe multiplayer or a new enemy like a giant or an enemy that alert everyone of your location or an enemy that sabotage your hacking or steal the artifacts away from you or a sniper like enemy, as for the difficulty I felt that the higher damage scale with difficulty is a bit redundant, so I suggest adding new enemies as the difficulty raises, or make the enemy shoot faster or shoot accurately, hell you might even give the player a more difficult mission that is only available on higher difficulty.

forgot to mention but is this inspire by csgo or other tactical shooter because I love the stop and shoot, and please add grenade, it would be awsome!
edit: might want a better screenshot since it's not all that appealing unless you play it, like a screenshot of the mainmenu, maybe the entire map itself
