They basically did a psuedo-shut down of my browser, saying viruses and other malware had been detected and asking me to download a piece of code/patch to fix the problem. The web-page imitates the Windows defense system and it’s easy to be deceived. Do not download or activate anything if this happens on your machine. Just close down your browser, or the tab, and run a full scan (I use Microsoft Defender) to be sure they haven’t polluted your machine any which way.
