Avast updated the free version recently. also Firefox added the facebook container. I have malawarebites running at startup for all browsers. Windows defender is not running since it used to be so restrictive, and I generally do not trust microsoft phone home appliications. Maybe I need to change this...... very tired of the continual windows 10 control freak issues. Maybe time to go to LinuxSounds strange. Did you install anything new? Perhaps try running Windows defender or malwarebytes if you already have it to see if there’s anything wrong on the security side first?
