Ok, but now explain like I'm 5 why the hell this is necessary?
Explain to me why you are checking if virtualization technology is available rather than if the current machine is a VM? Makes no sense, no game or software does this and it's plain stupid.
People do work on their computers, it should not be a choice between interfering with actual important software or a video game because the devs thought it would make any difference other than piss off people when they found out they wasted time installing a game that has stupid anti-cheat policies.
Fix your policies.
