    How do i stop it?
    Thanks

    As per the instructions :Please do NOT post any logs as an attachment. They will be - regrettably - IGNORED. Our members don't need long files downloaded to their computers; and if your computer IS infected, we SURE aren't going to download your files!

    Exactly what it says there. Do not post logs as an attachment. Yours is posted as an attachment.
    There are also other logs that you have not posted yet.
    As soon as you have followed the directions from the link provided, I will be happy to continue .

    It would seem that TAZNYU.SYS is a ROOTKIT.
    It can be removed with a ROOTKIT removal tool.

    Will you be posting the requested logs any time soon before the rootkit takes complete hold of your pc?
