  1. I have the HARE Virus in the boot sector. I cant run my Anti-virus becuase the PC restarts its self and when I go to TrendMicro.com for a Virus scan My PC restarts. :blackeye:

    Go to the following link and download the removal tool.

    F-Hare
    F-HARE will detect and disinfect the three known variants of the
    Hare virus (also known as HDEuthanasia and Krsna).
    Download: ftp://ftp.f-secure.com/anti-virus/tools/f-hare15.zip

    boot your computer into ms-dos with a bootable disk or floppy.
    Type fdisk /mbr
    Press ENTER
    Restart your computer
    Hope that will help you.

    Thank you I downloaded the F-HARE from F-Secure.

    I don't have a bootiable floopy disk, I never made one and one didn't come with my PC. Can I extract the F-HARE Application to a Floppy disk. Then restart my PC and when I get the black screen that has the "A:/ " can I type in what the previous poster stated ?

    you gotta make the floppy bootable
    ghost or nero can do that XP may have it's own utility for this I don't know don't use it.
    if you have an old windows 98 fdisk you can boot that remove it and put the other in do a dir/p to find the path

    Fdisk won't work from any old bootable floppy! It has to be a floppy with the fdisk tool on it, which ISN'T what the xp bootable floppy is.

    To run fdisk, you need a win98 startup disk, which you can create by downloading a win98 boot disk creator (I forget the address I got one from!)

    If you only want to boot to DOS to run a utility from a disk, then just create a bootable disk in XP by rightclicking on the a: drive and selecting format, then checking the bootable disk option. After you've created it, ad the utility to it. This is only any good though if the disk you want to run the utility on is FAT32, as the XP bootable floppy can't read NTFS.

    There are instructions Here for creating the boot disk with the removal tool howard suggested.
    i'm not sure just doing a fdisk/mbr would work completely as this is not the only info that resides in the boot sector...
    Hope this helps.
    patio :cool:
