Popup storm that warns of multiple viruses, MacAfee license fails and ads for it (phony of course), completely locks the browser from being used except for the ability to click on any of the popups. Trying to inspect by right click will bring up a related message to the popups so that's covered to. I eventually saw Comisopoa on one of the popups, looked it up in another browser, shut down the original browser (Edge) and eventually was able to get in the settings and block all notifications, which seemed to hide all trace of the problem. But some of what I've been able to research has said that if you have Comisopoa.co.in listed as a website that was previously allowed notifications, then there has been stuff installed on windows 10, so I'm probably going to reformat. Although scans show the entire system as clean. The attached jpg has some of the popups that I saw yesterday and comes from a site that recommends another product to clean it. ESET Smart Security was installed as soon as I could get it on there after the last Windows install and the browser integration is on all browsers.
