Error in Internet Explorer

I have been receiving an error on internet explorer for quite a while. When I get the error I get teh yellow triangle on the bottom of my page but I only get it on my email pages. When I have it I cannot delete my email by clicking empty or anything I have to open each one and manually delete. I have been able to fix teh error by repairing explorer but that stopped working. Then I downloaded ccleaner and ran it and it would get rid of the error. But now nothing is working and it is getting pretty bothersome since my junkmail will not delete itself in 24 hours either and I have to open them all to delete. Does anyone know of anyway I could fix this?? Any help is greatly appreciated
