This morning when I sat down at my computer there where two MS windows alert boxes open. The window title said "Messenger Service." They looked like legitimate error messages until I read the text. They were both ads for online scams. I googled the phrase and found a page with instructions for diabling this stupid feature of Microsoft Windows. Apparently your computer comes out of the box with the ability for anyone on the internet to send you one of these messages. Linux looks better and better all of the time.
