(888) 403-6260

Same thing! I got an email claiming windows defender detected virus/ spyware and about a blocked email. Upon calling the number listed here 888 403-6260, I heard a funny accent and so I claimed I mis-dialed. After calling again, I asked, "Where are you located", to which the guy stated,"In your mom's butt hole" then hung up on me. It's obviously not microsoft or defender. Don't be a sucker!

This is the call-back number on my screen claiming to be from Microsoft addressing a blockage of my compter.
