I agree, wording of the popups is just outright idiotic and scary for casual users. I've hated it ever since, but despite telling developers that they never changed the wording. At least me personally I've become entirely numb to the threats it makes, I just close the popup and move on not even really reading what it even says anymore.
This is what most of us are doing. The sad part is that if Avast
really had something important to pass along, most of us would simply ignore or,
not even notice that message.
