Claimed to be from the Windows software department and sounded like he was from Jamaica. Claimed they were receiving bad reports from my computer. Wanted me to type the Windows key-R combination to get the "Run" box to pop up. Was going to have me type something in there to run, when I questioned if they were from Microsoft as Caller ID did not indicate as such (Unavailable). "Well! Well! Well!" and hung up. Scam!
