Please move this note to the appropriate sub-forum.
After replacing a router today I was immediately bombarded with this threatening warning (see screen shot attached). A voice over said I was infected with a (particular virus) and that my computer would be destroyed in 1 hour and 34 minutes unless I called the number shown immediately. On calling the telephone number I was told by a foreign-sounding agent that I was talking to "Microsoft engineers at Tech 247." At that point I hung up and did not get the rest of his pitch.
I did do an Avast scan and found I had no viruses.
I am pretty sure this was a fraud. Is there nothing that can be done to shut down these vultures? Who ought to be notified of these attacks? What do other G-t-Gers do when these pp up? ...batpark
