Computer Immunization in MBR (Master Boot Record)

[HR_Luka]

Hello, recently I've heard there is a way to "immunize" my PC from Boot-Up viruses. I've been looking for it all over the Internet but couldn't find anything. Any link to this application/routine is helpful or you can post how to do it. Thank you!

Thank you for your reply, I appreciate this and I will do it as soon as i see a virus on my computer. But, however, I am really scared of Boot-Up viruses because they cant be detected as they are written in the Master Boot Record and as soon as the computer boots they are copied into the RAM before the Anti-Virus program. As I mentioned above that free space in Master Boot Record where the Boot-Up virus is written, can be written with some programs or some routine, im not entirely sure with what, thats why im asking, so there won't be free space and boot viruses cant be written. Hope i cleared something if not ill choose your reply as answer.

Luka
