Reinitialized is NOT a low level format. Also doing even that is<br>
complete overkill. Simply overwriting the disk with zeroes is plenty,<br>
and even that is overkill. Writing a new filesystem and partition table<br>
would be enough to wipe any link to any software on the disk.<br></blockquote><div><br></div><div>Overkill I can live with but if this root-kit trojan has a mechanism that actually goes and resides in the BIOS then we are right royally screwed ? And wiping the disk is not going to help ? In that case flashing the bios and in extreme cases actually pulling out and puting the bios chip back is the only solution ? So YES agreed it is overkill but liek I said better to be safe than sorry with no back up of countless hours of data. ( Yes I had to do this long years ago :-)<br>

And yes fdisk /mbr used to overwrite the boot sector with a default<br>
loader and hence would wipe out any boot sector virus present there.<br>
