Pandainterface Error on Domain Controllers

While checking logs on my two domain controllers today I found the following errror on both servers.  I have not installed anything new on the servers in months, and no users have access to the servers so browsing to an infected site is unlikely.  Does anyone have any information on this 'pandainterface' error?
Thanks,
Joe
