Affiliate Marketing Secrets

I had this company call my home number claiming to be affiliated with Windows, telling me there was malicious software on my computer. I instantly suspected something fishy, but I played along – cautious as to what info I told them.
They told me to Run the “Event Viewer” program, showing a bunch of errors and warnings. She then told me to go into my computer data to retrieve a 6-digit number from my product ID, and enter it into the Technical Support section on http://www.globetechzone.com/ – allowing one of their workers to have access to my computer. That is where I drew the line. She then told me my systems were out of date, and I needed to pay $115 to update my system. I promptly hung up.
So have any of you heard of globetechzone and is it a scam?
