Iexplore- memory could not be referenced

Internet explorer keeps displaying a error message every few days stating that memory could not be referenced with some numbers and letters (perhaps co-ordinates of sorts to where the error originates) but my admin logs havent logged it and Internet Explorer hasnt crashed it stays open

any help would be appreicated

Please, post a screenshot (see how: http://forum.avast.com/index.php?topic=8982.0).
You can use Gadwin PrintScreen to get a screenshot (http://www.gadwin.com/printscreen/) or the free version of WinSnap 1.1.10 (http://www.filehippo.com/download_winsnap/?2173).
