Hi,
I have used Avast free without issues for years now. After last update there has been a black user interface. I have restarted computer, tried repairing installation. Nothing helps. Text on the black windows says that I am still protected, but I can't do anything. The real User interface is behind the black cover. As Attachment there is a picture of the black screen.

Edit: My OS is Windows 10, so newest Avast version should be supported. This black screen prevents me to even see the Avast settings. Could Avast be hacked?
