Black screen on videos

I like AVG Ultimate , best protection software ever

But Since I using AVG I see black screen on half of my videos and video clips are black.

I have sound but its black. How can I fix this?

Hi Jozsef,

This shouldn't be due to AVG.
Are you experiencing the issue on your Windows computer?
