What's the deal with the virus/spyware alert messages that are coming up when I mistype a web address? I recently tried to go to androidcentral.com and must have mistyped part of the address. What came up was a norton anti-virus page with a popup that would not go away no matter how many times I clicked the X. There was also a recorded message saying to call this number as soon as possible. I had to completely close Chrome in order to get the message to go away. Another similar situation happened a while back. A website I was going to had a dash in the address and I forgot to put it in. A loud siren type noise played through the speakers while a virus/spyware alert page was open in a tab.
