The MBR virus which destroys the PC system after booting has been founded recently, thus users require special attention on their security. 

If a user PC is infected by MBR(Master Boot Record) virus, the virus will hide itself in the PC until user starts the PC,  then it will destroy the system files after booting done. In this case, system recovery is not possible and OS must be reinstalled.

Therefore, please beware of malicious spams or files on using PC, and maintain the latest ViRobot engine version all the time.

HAURI have done the update for MBR virus, so users can detect/repair the virus from engine ver.2010-01-28.01 or above.
