Avast blocks my internet connection

Turning off this shit makes my internet working back. When it’s turned on, my internet is EXTREMELY GO SLOW OR JUST STOPPED with somekind of DNS blabla bullshit. My other devices which also using same network doesn’t have this issue. It’s really fucking annoying.

And how da fuck disable those annoying product ads popup shit?! I even used Avast Secure Line several years but still asking me to use this shit!
