I am confused that Defender and Webroot did not flag this virus.
What virus? Did your scans catch any viruses? Probably not, because this type of attack is known as a browser hijack. It exploits features built into the browsers.
2 things to do:
Disable notifications from all browsers. Start - Settings - System - Notifications & actions, scroll down and turn off notifications from all web browsers that are listed there.
Install the free Malwarebytes Browser Guard if it's available for the browsers in use.
