Man with East Indian accent calls, claims to be with Microsoft, says they have received signals that my computer sent out, showing that it's having problems. Asked me to read him all the icons on my desktop. Oddly, got transferred back and forth between two people. Asked him to give me a license number to prove he has access into my computer.
Started to read me a "license number" beginning with "8" and I finally got mad and said, "prove to me that you're not a scam!" He immediately hung up.
