This program was blocked by an anticheat service for riot games, and while the game is in beta just a little thing that is probably good to know

CPU-Z is a free tool that collects information on some of the devices of your machine, such as:

* Processor name
* Mainboard and chipset name
* Memory type, size, etc
* Real time measurement of each core's internal and memory frequency

It's a legit driver, so I guess Riot will fix the issue and accept this cpuz148_x64.sys file in the future.
