Hello!
I have a problem I cant turn off the avast schield. When Im right clicking and trying to turn it off, it does nothing.

You right click the Avast icon in your system tray then follow this:

If using the right click doesn’t open this pull down menu, do a repair of Avast:

Control Panel> Program and Features (Add/remove program)>Select Avast> Select Repair. Reboot when completed
