I just got a call from "Steve Wilson" from OS Advisor wanting remote access to my computer. These scams are common, in case you are wondering how to tell, here is the page with tips from Microsoft. Luckily it is one of the top results when you search for "OS Advisor Scam".
The crazy thing about this is how brazen the attempt was: Steve said his company was authorized my Microsoft and that the "Mother Server" for Windows had received a message from my computer. Recently, On the Media did a piece on the Nigerian Prince scams -- and why they are still around.
The design of the scam is to only draw in the most gullible people. If you are willing to believe that there is a "Mother Server" or a Nigerian Prince -- you will probably be willing to do the other stuff they want -- like send ten thousand dollars or turn over access to your computer and your credit cards.
What a crazy world we live in. Sure makes getting the real marketing message through the noise a lot harder.
