Security Essentials 2010 as reported here
http://www.theregister.co.uk/2010/02/26 ... als_rogue/
is a phoney virus designed to part you from your money much like other scams that have been around these last 5 years (Antivirus 2009 & Windows Antivirus 2008 were two variations)
I already have one customer with it so it exists out there and is not just something to read about.
The main difference is the change of name to make it look as though it is the genuine Microsoft Security Essentials product, it isn't, it's the same old scam.
