How to clean Defo virus in the MBR sector?

Question

I have Defo (Virus DEFO.MBR) virus in the MBR sector which Eset Antivirus can detect but its unable to clean even MBAM and Spybot are unable to find it. Any way that I can get rid of this?

Answer 1

Make this F-Secure rescue CD, boot from it and clean the infected MBR

Answer 2

There are a few ways to do this and I found a few sites that talk about this virus.

First off you might just need to rewrite the MBR from what I am reading about Defo but either way here are some links to remove this.
