I had recently built myself a new computer. It had been working fine for the most part but occasionaly IE would crash and completely shutdown. It would happen maybe once every day or two. I thought I possible could have a memory issue but I ran memtest overnight and my memory was fine and also no other applications were acting flaky. anyway, msnff.dll was the module causing the error in IE but I have not figured out what exactly this file is. I can't find anything on the internet about it. I believe my error had something to do with the msn toolbar and possibly the password manager that is included with the msn toolbar. I removed the msn toolbar and have not received the error since. Does anybody know anything about msnff.dll? Has anybody else run into this error? The windows xp event viewer gave me very little info other than the dll name.
