alt=""? tags in dolphin messages

I haven't seen anything like this out there yet so hopefully I can get some help.

I am getting this odd looking message discription with alt tags whenever I make a change, log in or delete evets etc.  I even got one that said "this may be a hacker string" but have not been able to duplicate it since.  The first time I got that was when I deleted one of my classifieds.  Since then this is about all I have been getting.  HELP!
