    Had a similar issue to this thread, so I followed your instructions for removing Trojan:DOS/Alureon.A on this thread. Logs attached from MBRCheck and tdssKiller.
    I ran the tools in the following order:
    1. Windows Security Essentials reported finding Trojan:DOSAlureon.A. I then searched the web after it keep coming back after multiple runs of Windows Defender Offline. Thankfully found this site and started the cleaning process.
    2. Downloaded recommended tools
    3. MBRCheck (Infected MBR found)
    4. Reboot into safe mode
    5. tdsskiller (Rootkit.Boot.Pihar.c found and cured)
    6. Reboot
    7. tdsskiller
    8. Reboot
    9. MBRCheck
    10. Reboot
    11. Windows Security Essentials scan
    Removal seems to be successful. At this point I would like to know if you would suggest running bootrec like is suggested on the Microsoft Malware Protection Center?
    bootrec /fixmbr
    bootrec /fixboot
    bootrec /rebuildbcd

    Welcome to MajorGeeks, spacelatch :)

    Not necessary as TDSSKiller has basically done the same thing. However, these infections usually leave another trace that can be seen by scanning with TDSSKiller with the Change Parameters => Scan for TDLFS File System toggled on.

    If you see TDSS File System, then you can opt to Delete it and that should be the end of the infection.

    thisisu,
    Thanks for the reply. I ran TDSSKiller with 'Scan for TDLFS File System' enabled and it did find a TDLFS file system which I removed. Everything on my machine seems to be running fine and dandy now.

    Thank you for the help and thanks to Major Geeks for the info on how to get rid of this nasty malware!
