    Performed request because I trust you.
    I got:
    “DllUnregisterServerinC:\Windows\system32\shimgvw.dll
    succeeded.

    Woo!

    What did I just do?

    Thanks Mike!

    What you did is disable Window’s ability to indisciminately open picture files, which is how the new exploit spreads. You have just made your computer safe until MS patches the vulnerability.

    Oh.
    So that explains why my Windows Picture and Fax Viewer no longer works. As I realized about 30 minutes ago.

    It’s great to have security, but I use the viewer. So next question:

    How can I use it for my own selfish and personal needs?

    Right now I am using paintdotnet.

    Thank you Steve for answering, because I had forgotten I listed to Mike last night.

    LOL

    That’s a good question, because I have the same problem. I will look into a temp fix until Microsoft updates the DLL.

    Thanks Mike.

    It is a frustration, but glad I am not the only one!

    Let me know how to go around it.
