still havent figure out what silent gaming mode does but dont think its what i need now

Eddy's suggestion is:

Look for the Avast tray icon → right click → Avast shields control → Disable for…

Be aware, disabling the shields, you are less protected.

diabling sheild control doesnt help, I dont know whats wrong with 3dmark11 but been told its avast so wanto find out by disabling the whole program

do i need to uninstall it?
