The Red sheld is a fake and has nothing to do with Windows. I am surprised that this has not been identified by anyone yet.

I have had great difficulty in successfully removing this and i nearly always backup important files, Format the Hardrive and re-install Windows, i found this the only 100% way to clean it.
I have known it come from various forms, most commonly the 'post office virus', take a look at www.Snopes.com
Have a look at your Desktop Properties (right click desktop and select properties). if you get 3 tabs only then sorry, wipe your system and re-install. if you get 5+ then you should be OK.
If i ever see that sheld on anyones PC......i'll format the drive......no messing.
