"Drag anything to right for searching and to left for sharing"

Just got back from out of town for a month and, in addition to Windows saying there are no new updates to download, which seems unlikely, every single website I visit in Comodo Dragon causes a pop-up window to appear:

"Drag anything to right for searching and to left for sharing"

There is a button which says "do not show this message again" but it seems to have no effect.

This doesn't occur in IE, and I haven't seen it happen in Comodo Dragon on any of my other systems -- but then again my other systems are all getting an "NSIS Launch Error" which is supposedly a Comodo installer failing to launch.

So perhaps this is "legit" software from Comodo that has failed to install on my other machines?

Or perhaps it's Malware?

The oddest thing is that I can't find any trace of this pop-up message on google.

 

Never mind, found a poorly worded support forum post suggesting this is a new bugfeature.

Sorry, can't delete post.
