When you close an Internet Explorer browser window, you may receive the following error message:
Iexplore caused an Invalid Page Fault in module Kernel32.dll
Clicking OK closes the error message dialog box.
One possible solution is this one that I got from Microsoft.
This behavior can occur if the McAfee VirusScan version 5.x Internet Scan and E-mail Scan tools are enabled. This issue might occur with only one Internet Explorer or Outlook Express window open, but happens most often when you close one of several open windows.
Contact McAfee to inquire about a possible patch or upgrade that resolves this issue.
To work around this issue, disable the Internet Scan, E-mail Scan, and Internet Filter functionality in the McAfee software.
cheers!
