This morning my antivirus software, Avira Antivirus Premium 2012, began identifying threats on Stack Exchange pages. As far as I can tell, it identifies the same threat only on
The threat was found immediately on:
But not on:
On closer look it appears that the resource in question is the script that runs both the formatting bar for editing questions and answers, and the live preview of one's post. Both of these are disabled when I deny access to the identified resource:
It appears that the reason the SuperUser question did not raise the alarm was because it is a locked question and so the edit bar and live preview were not available. When not logged into a site, the resource isn't loaded until the answer box is given focus. When I attempted to answer a question on a site I was not logged into the same warning appeared.
Here is the message given to me by my antivirus software:
Finally I should note that my antivirus software is up to date, but I'm not sure whether the latest update happened between last checking Stack Exchange. If the script in question has not recently changed, I suspect Avira Antivirus's most recent update is to blame.
Either way, I felt that the SE team should know so that they can fix their script or contact Avira, as necessary.
