    Hi,

    I'm having problems removing Win32\Agent.CR from Windows\System32\Win32l.dll (Windows 2003 Server) with Forefront Client Security.

    It is classified as a backdoor and risk as Severe.

    If a choose SmartClean button it saids that it needs to restart the server because to remove it. But after restart, if I scan, it is there again.

    I used tasklist to identify the program that is using it. It is msiexc.exe.
    I killed the process at task manager and try it again. It seams to remove it. But if I restart the server and scan again. Yes, it is there again!

    How can I remove it? Could it be a false positive?

    Thanks,
    Pedro Gonçalves

    Get a copy of the file and submit it at http://www.microsoft.com/security/portal use the submit a sample button.
     Guessing our detection/removal rules may not be just right for the variant you are seeing and need to be updated.  Be sure to include details when submitting it.
