I have some users who have computers with Internet Explorer 8 installed. 4 users in particular are starting to receive crash errors of Internet Explorer when it is not being run on the machine. Meaning, there is no instance of Internet Explorer running when the crash message pops up onto the screen. There is no reason as to why the error message is popping up. 2 users have other web browsers as their default web browser and never use Internet Explorer to begin with. Sometimes the only open program is Outlook 2010 (Standard, SP1) and the error message pops up. The error message occurs about every 15-20 minutes, greatly affecting productivity.
The computers are fully updated with the latest Windows updates. I am running Windows XP SP3 on them. All add-ons have been disabled for Internet Explorer for all users and the error message is still happening. Full virus check performed with Kaspersky 8, found nothing. Other users on the same domain are not having these problems and Internet Explorer will work for them. Just not for these people.
Short of reprofiling them on their own computers, does anyone have any ideas as to what is happening?
