I got a pop up on my MacBook Air, on Safari, with url://managemyhomepage.us. The message appeared to be from Microsoft informing me that some spyware may have caused a security breach. I called this number and someone with a thick Indian accent, going by the name Alex Martin answered wanting information to get remote access to my computer. He said it was the only we I could get his resolved. I told him I would call back and hung up.
