Hello,
Today I got a Windows Denfender fake attack. It took over my whole screen and I couldn’t get to the back of the desktop to unplug the sound bar. It had a number to call for help. She answered and asked for the OS and my name. I thought again and hung up. I put a pillow over the sound bar and used ctrl+alt+delete which it said not to do. Anyone else? It was very alarming for me.
Here is a Norton blog on this issue.
