Summary: Riot Games, which is funded by Tencent, the Chinese CCP media giant, installs a driver called VGK.SYS that uses root access on your Windows / Windows 10 operating system. This is a huge security backdoor/vulnerability that could be abused at by both Riot / Tencent themselves, and by 3rd party hackers.
It was news to me that Riot is supported by Tencent - will no longer be patronizing their products.

A tent
With a screen door
With a $100 padlock
and the camel is already in the tent...
