Hi - Out of nowhere when I go into my regular Yahoo Mail account, I got a whole page takeover that said, "This site says... Internet Security Alert! Code: 055BCCAC9FEC. Internet security alert: Your Computer MIght Be Infected By Harmful Viruses." etc. etc. It says to call Windows Technical Support at (855) 334-3967. I took a picture of this page takeover to reference, if needed. I just ran your scan for anything harmful and it came up fine/excellent. Can you help me figure this out? It's happened a second time after the first time, so it's not going away. Thanks!
