This window keeps popping up and I can't get rid of it. I searched the internet but found no answers, i tried to delete History.plist and LastSession.plist and Downloads.plist files to the Trash from ~/Library/Safari.

But this didnt work,

 

anyone know what this is?

    I'm seeing exactly the same error message, with exactly the same random (or, it turns out, not sot random) string.

    I looked into the logs in Console.app, hoping to find which application keeps trying to open this URL, but could not find anything.

    I've got the same on a family member's Macbook Pro running 10.9.5.

    I first figured they are running or clicking something odd, but seems it just comes up on its own.

    Very mysterious.

    I had the same sort of message when trying to open a URL from a Google search results list. I don't know if it is relevant but it turned out the site it was pointing to was a nasty web browser hijacking infested site.

     

    The URL did open normally in Firefox and AdBlockerPlus in Firefox blocked the nasty stuff.

     

    Might be something new from Safari 10? Or if everyone else is hitting these URLs via Google perhaps Google are doing something.

    The thing is, no one seems to be clicking on any links in our case. It is as if something at OS level (or dodgy application that is not being picked up by BitDefender) is making the call...

    Digging around, this may be caused by Skype (ads).  Here is a page in German discussing the issue and using a /etc/hosts file to block the ads.  I don't use Skype on Mac, so good luck to those trying to solve this problem.  Hope this helps.

    OH!!!! That's it King man Leon.

     

    They were running Skype on the machine which is affected (for me at least).

     

    Translating the solution from ioffer007

     

    The solution is:

    1. Open Terminal

    2. sudo nano /etc/hosts

    3. (enter your password)

    4. Add to the existing list:

     

    127.0.0.1 rad.msn.com

    127.0.0.1 live.rads.msn.com

    127.0.0.1 ads1.msn.com

    127.0.0.1 static.2mdn.net

    127.0.0.1 g.msn.com

    127.0.0.1 a.ads2.msads.net

    127.0.0.1 b.ads2.msads.net

    127.0.0.1 ac3.msn.com

    127.0.0.1 apps.skype.com

     

    5. Ctrl-O, RETURN, Ctrl-X

     

    (you are basically not allowing the ad URLs to leave your computer with this modification)
