Valorant has a kernel level ~~rootkit~~ anti cheat that only works with windows, so Linux won't work. It also refuses to run in virtual machines.

To clarify, I do not mean that the anti cheat itself must be malicious, but one more program running with kernel access is one more attack vector that attackers could use.

It is malicious because it forces its weird registry key or something to startup before the OS even realises its booted. Its a straight virus in my opinion.
