What is Avast!

Avast is the US of the antivirus. You try to make us feel weak and vulnerable. Each day you tell me how much terrorist attack you stopped. I’m supposed to enjoy taking a ride on the internet, not fearing turning my PC on. I do understand that you want to terrorise me enough to make me pay for an upgrade, but It’s so obvious… Upgrading my antivirus under those terms is like voting for Trump… It doesn’t make me happy and it will probably make me never vote again.

Put your shit together and be the gentle old lady across the street, not the FBI guy in the handyman’s truck.

As has been explained many times, you can disable the offers for avast products in the settings if you have a paid version.
Or you can set avast (not recommended) to silent/gaming mode.
