(MBR)/Boot Sector Infectors i.e; Viruses & Trojans??

Hi, i have been reading this thread;

https://www.wilderssecurity.com/showthread.php?t=104854

i was wondering how easy it is to detect and remove a MBR Trojan etc from a general home machine? And does a general format really kill this type of infection and comprimise? If your antivirus or Trojan software isnt picking it up how could you manually detect it on your machine?

I know alot of questions, but i am interested and would like to know for future reference,

Thanks Avec

This type of virus takes control of the system at a low level by activating between the system hardware and the operating system. An MBR/Boot Sector virus is loaded into memory upon boot-up, before virus detection code can be executed.''

 

i think general format should clean this boot sector infector but sometimes it won't.
