The rootkit isn’t a solution. It’s a bandaid - and a bad one at that. Moba and FPS hacks have already moved outside the hardware of the PC or into the virtual space. It’s a beware of dog sign on the fence meant to scare users… while ultimately doing very little (besides providing a vector real hackers and tools can exploit to gain access to your system.)
Seriously anyone willing to install a rootkit on their system that that company is behind deserves whatever comes their way next.
