    I think so, but checking.

    I use Active Kill Disk (its free and a great thing to have to wipe the partitions) - google it for the download.

    edit: nvm - here's the link just to make sure you don't get anything unwanted trying to find it.

    Burn it to a CD & boot from disc.

    MAKE SURE you burn it as a bootable disc (image/ISO) otherwise it will not work (it wont be able to boot from the disc)

    If you need a free software to burn ISO's, I use IMGBurn. Link for that is:

    Wipe all partitions before installing the OS.

    Once you wipe that, the only thing that is left once you reinstall the OS is going to be whatever comes with the OS installation disc.

    Yes, but don't reinstall it from a backup. It is also possible to kill it with anti virus utilities. TDSS Killer did it for me on an old XP machine that had a very nasty rootkit. Go to It took me a long time to finally get rid of it. It was better than reformatting, reinstalling, reloading software and data though.

    In general, yes. Which Rootkit has infected your computer?

    Thanks for all the replies. I'll wipe all drives clean and re-install from original Windows CDs.

    I don't know what it is, but it's nasty. It turns off ANY antivirus software I put on. It does not show any infection on tdsskiller, and several other killers (kasperesky?) I tried. I went to bleepingcomputer and tried several of their recommended products, NONE showed an infection. But my searches always get redirected and my dns is not rerouted.

    I'm so fed up, that I'm going to bite the bullet and wipe and reload.

    it's worth trying the security tools at

    you can run them from about anywhere. flashdrive, cd, or a spot on your windows desktop

    try one of the browsers from portableapps. see if searches get redirected.


    also, if you do decide to wipe everything and start over, take the
    time to make a second partition on your hardrive. very handy for storing data while messing with operating systems.

    also, make and use a limited windows account for surfing. that way if it gets messed up you can use the admin account to delete the messed-up account and make a new limited acount for surfing.

  7. You need to get something Linux based that boots off CD or flash drive.

    A lot of these things will re-write themselves into something
    else. Once your anti-virus kills off the old thing the new thing
    will re-install itself or re-download itself when you connect to
    the internet.

    A linux based anti-virus will not trigger the existing virus to replicate
    as it won't have been loaded into memory allowing it to be cleaned.
    Did this to my step-sons computer after he picked up some nasty
    thing from too many porn sites. I think it was the Avira one I used.

    All the Best,
