    Hi guys,
    I need help badly, got the same problem as the rest; the Backdoor.Sdbot virus was found on my system a while ago. I thought I fixed it with avirus scan but now I cant seem to get connected to MSN. It says there is a newer version available but I cannot install it. When I download the new version and try to install it it keeps telling me setup.exe is not a valid windows32 appplication.
    Anyway I downloaded HijackThis and got the following LOGFILE. Can Anyone help me please......???? (IN the mean time I have fixed F0 and F2 already)

    Logfile of HijackThis v1.97.7

    Run a new HJT scan and put a check beside the following objects in the list.

    F0 - system.ini: Shell=Explorer.exe F:\WINNT\system32\System32.exe
    F2 - REG:system.ini: Shell=Explorer.exe F:\WINNT\system32\System32.exe

    O16 - DPF: {E0B795B4-FD95-4ABD-A375-27962EFCE8CF} (StarInstall Control) - http://install.serviceurl.de/StarInstall.ocx


    Close all application windows except HJT. Close all browser windows, including this one. Click the Fix Checked button.

    Restart your computer and post a new HJT log

    Please let me know if this fixes your problem.
