Write protect boot sector

In my BIOS setting I see the option to write protect the boot sector to protect it from viruses.  I wonder why nobody recommend this in the forum?

2

Can I suggest some reasons

 

1, The forums are centred on Norton products and not bios settings of computers

2. The incidence of Boot sector virus has diminshed since bootable floppies retired.

 

3

I thought that enabling boot sector in the harddrive can prevent viruses such as TDDS which infect boot sectors...

There are Bootkits like Whistler, Mebroot group, alipop, and now Boot.Tidserv variants that looks like will keep going as the TDL3 site has been looks like shut down.

 

They don't need a Floopy Drive at any stage.

I think having the knowledge to back up and restore it would be good. Just mentioning it has nothing to do with the 'forums because they are centred on Norton products and not bios settings of computers'  is sticking the head in the sand and not helping the OP, sorry.

 

Below are two Symantec documents which offer some more information:

I mean will enabling write protection of boot sector through BIOS prevent the bootsector viruses like td33?

7

Does turning on write protect boot sector help prevent boot sector virus like tld3?
