On a Windows 7 system that came with avast! Free Antivirus preinstalled, whenever I was browsing the web with Internet Explorer 9, I would periodically see "Internet Explorer has stopped working" messages. When I clicked on the "View problem details" link in the window that appeared, I found the problem associated with the avast! antivirus program's asWebRepIE.dll Dynamic Link Library (DLL) module.
