MVP's are Microsoft Most Valuable Professionals. The award is given to those who show outstanding achievements, in a voluntary capacity in the Internet/Microsoft communities. I got started as a Malware Removal expert, later becoming a Staff member (Global Moderator) and author of the Windows Security Checklist at CastleCops. Microsoft had awarded me MVP from 2006 to 2009. I was not awarded again in 2010, largely due to some serious illness suffered in 2009.
CastleCops Staff also helped myself and Nancy Altholz to research and write a book called "Rootkits For Dummies" via Wiley Publishing Ltd, 2007. It came out the same day as Windows Vista. Unfortunately, CastleCops closed its doors sometime ago. I had been there for six years.Rootkits for Dummies is still for sale and available from many regular booksellers, including Amazon. It's a bit dated but the basics of good security are all there. If you want to learn more about how to secure your computer check the Blog entries and Off the Wall.
