My computer was being non-responsive, so I rebooted. When I got back to my Desktop, I saw a dialog box/window open for Avast. It had updated the virus definition list and/or the software. But I also happened to catch (just in time) two check marks in the lower left-hand corner. Apparently, Avast anti-virus is now in the browser business.
No thanks. Stick to your knitting, ass-monkeys!
