Reinstall or fix regedit

Discussion in 'Virus Information' started by Herman Griffin, Oct 31, 2004.

  1. I think I have some sort of virus, and it may be the sort that renders
    Norton Antivirus useless. At first I was having trouble updating my virus
    definition file using LiveUpdate. So I downloaded the update directly from
    the Symantic website. The went fine. Now, when I run a virus scan on my
    system my computer crashes part way through. Sometimes it scan longer then
    other times, but it never finishes. I tried to use regedit to remove any
    virus-created entry in the Run, RunOnce, etc key's. But when I run regedit I
    get an error that reads, "This application has failed to start because
    db.dll was not found. Re-installing the application my fix this problem."
    Does anyone know how I can re-install regedit with out reinstalling Windows
    XP or how I can fix my regedit problem? Thanks in advance. A direct email is
    fine.

  2. Can you run regedit if you boot into safe mode?

  3. 1) Download the following three items...

    Trend Sysclean Package
    http://www.trendmicro.com/download/dcs.asp

    Latest Trend signature files.
    http://www.trendmicro.com/download/pattern.asp

    Adaware SE (personal free version)
    http://www.lavasoftusa.com/

    Create a directory.
    On drive "C:\"
    (e.g., "c:\New Folder")
    or the desktop
    (e.g., "C:\Documents and Settings\lipman\Desktop\New Folder")

    Download sysclean.com and place it in that directory.
    Dowload the signature files (pattern files) by obtaining the ZIP file.
    For example; lpt202.zip

    Extract the contents of the ZIP file and place the contents in the same directory as
    sysclean.com.

    2) Update Adware with the latest definitions.
    3) If you are using WinME or WinXP, disable System Restore
    http://vil.nai.com/vil/SystemHelpDocs/DisableSysRestore.htm
    4) Reboot your PC into Safe Mode
    5) Using both the Trend Sysclean utility and Adaware, perform a Full Scan of your
    platform and clean/delete any infectors/parasites found.
    (a few cycles may be needed)
    6) Restart your PC and perform a "final" Full Scan of your platform using both the
    Trend Sysclean utility and Adaware
    7) If you are using WinME or WinXP,Re-enable System Restore and re-apply any
    System Restore preferences, (e.g. HD space to use suggested 400 ~ 600MB),
    8) Reboot your PC.
    9) If you are using WinME or WinXP, create a new Restore point

    You can also try some of the below online scanners.

    Run http://invircible.com/download/fixregex.com right from the server (no need
    to download the file to the local drive). This will restore the functionality
    lost, to REGEDIT and to other applications.

    Only *after* having run the above, do as suggested by David H. Lipman, in this
    thread.

    Get yourself some decent AV protection!

    I think your best bet first is to boot into safe mode.
    Have a copy of the most recently available updates from
    nortons. Install that while running in safe mode. Check
    your registry see if you can through safe mode. And also
    do a complete virus scan in safe mode.
