It seems like more and more calls I get to my landline are total BS. Either automated messages, or in the case of this creep, telling me that my computer is "infected", since he SUPPOSEDLY works for Microsoft.
"Listen a**hole, I'm a computer PROGRAMMER and KNOW that you DON'T work for Microsoft and I DON'T HAVE A COMPUTER VIRUS and you're not getting my ISP address" got him to promptly hang up.
