    Question about removing a Backdoor Trogen

    Norton Antivirus says I have a virus called Backdoor. Trogen that it can't clean or quarantine. It is located in C:\WINDOWS\System32\hlppafd.dll . How can I remove it?

    You sure it isn't Backdoor.Trojan?
    From: http://securityresponse.symantec.com...or.trojan.html


    The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.

    1. Disable System Restore (Windows Me/XP).
    2. Update the virus definitions.
    3. Restart the computer in Safe mode or VGA mode.
    4. Run a full system scan and delete all the files detected as Backdoor.Trojan.
    5. Reverse the changes made to the Windows registry.
    6. Windows 95/98/Me only: Remove any references to the infected files that have been added to the Win.ini and System.ini files.

    For specific details on each of these steps, read the following instructions.

    This may sound dumb... But did you run the update on The Cleaner before you did the scan ?

    I have found that if NAv detects it.. the Cleaner will remove it..more to the point.. The cleaner has (for me) detected and removed Virus and Trojan's before NAV will detect it..

    Cheers
