  • How to deactivate Adobe Digital Editions

    Matt Fahrner

    As found on an Adobe Forum…

    To deactivate a PC with Adobe Digital Editions 1.x:

    1. Launch Digital Editions 1.x
    2. Enter the key-combination of <CTRL><SHIFT>D (<CMD><SHIFT>D on Mac OS)
    3. At the dialog, confirm that you wish to de-activate the machine
    4. Quit Digital Editions

    To reactivate and authorize the machine using the same or a new Adobe ID, just re-launch Digital Editions. You will be prompted to activate.

    This can apparently solve a number of random issues with Adobe Digital Editions. In my case I needed it because I used the wrong Adobe ID to activate!

  • Useful browser check…

    Matt Fahrner

    Apparently a lot of compromised browsers purposefully send a modified “UserAgent“, for instance:

    UserAgent Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1;
    AntivirXP08; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.1; .NET
    CLR 3.0.04506.30; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022)

    that “AnitvirXP08” isn’t supposed to be there and best guess is it helps web sites that work with these viruses/trojans know the system is compromised.

    A web site to verify your agent to see if it has one of these is:

    http://whatsmyuseragent.com

    Unfortunately I imagine in time they’ll mask these a little better, like putting a bugus “.NET CLR” value that looks close enough to make it hard to see, but isn’t real and they can identify.
