Didn't leave a message. Called the number back and it asked if you wanted to be removed from their call list

Caller said he was from Microsoft Tech Support. Told me that my computer had been compromised and was downloading all sorts of malicious software to my machine. Fortunately, I'm an I.T. professional, and I knew it was a scam.

Now here's some helpful info to pass on; call 866-246-7196 scam to be added to a do not call list. This service is only for a small number of companies that call consumers but it works for this caller. First give the caller's phone number to confirm it's on their list and the receiving phone number to add to the do not call list.
