Hi rgrant1993, you compare your program with Game Booster which shuts down unnecessary Windows processes for gaming.

Game Booster is an easy-to-use program that shuts down unnecessary system processes in order to improve the performance of resource-thirsty games. With an intuitive interface that makes it easy to switch between gaming mode and normal mode, Game Booster is a simple but powerful program.

Firstly: Avast processes are not unnecessary.
Secondly: I doubt your program will get past Avast’s defenses.
Thirdly, I believe the latest version of Avast already has a gaming mode which stops popups/updating.
