    Spybot tells me that I have a "DSO Exploit", which seems to be some exploit of MS-IE and/or Outlook. It suggests I look it at security.greymagic.com/adv/gm001-ie . That link discusses some issues concerning active scripting and dynamically injected html code, etc. etc. witht he bottom line being to do the following:

    There is no configuration-tweaking workaround for this bug, it will work as long as the browser parses HTML. The only possible solution must come in the form of a patch from Microsoft.

    Update - 3 Mar 2002

    Since the injected <object> runs in the "My Computer" Zone changing the Internet Zone's settings didn't affect it, but changing the correct zone's settings will prevent this exploit from running.

    Here is the registry information:

    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\0]
    Change the value of "1004" (DWORD) to 3.

    Many thanks to Axel Pettinger and Garland Hopkins for this workaround.

    Does any one have any insight or similar experiences?

    Can you please tell me whether the above is good advice and how specifically I can edit the keys if it's good advice (e.g., with regedit or regedit4??) ?

    Here are a couple threads on this issue. The fact that Spybot finds the problem but can't fix it, is just a bug in Spybot v1.3. You can ignore it if you are current with Windows Update patches. (In fact, the patch for this came out about 2 years ago, so if you've done Windows Updates in the last year, you are probably no longer vulnerable to the exploit regardless of the setting Spybot finds).
