Error message in mfc42.dll appears when starting, and the Internet Explorer quits:
http://support.microsoft.com?scid=kb;EN-US;Q813181


There are a few variations out there involving....

 

xupiter.com; browserwise.com; sqwire.com; orbitexplorer.com

 

Generates pop-up advertising, hijacks search engines, adds links to Internet Explorer, automatically tries to update itself.

 

Xupiter is the most likely cause of the following error:

Explorer caused an invalid page fault in MFC42.DLL

 

NOTE:  Malware known as 'Browserwise' causes the error 'iexplore.exe caused an invalid page fault in MFC42.DLL'

 

Its presence, or a faulty uninstall, is implicated in the following error (unconfirmed):

failure sinking events IWebrowser2

 

It is also known to cause crashes involving the file xtupdate.dll and sundry other xt*.dll files.

 

An uninstall facility is available at the link below:

http://www.xupiter.com/uninstall/

 

The "orbit" version can have an entry in add/remove programs.

 

The inexperienced computer user can get rid of Xupiter by running:

 

1.  AdAware (available at http://www.lavasoft.de/)

 

and then...

 

2. BHODemon (available at http://www.definitivesolutions.com/bhodemon.htm)

 

An excellent replacement for AdAware is Spybot. Again, it is a free programme which can be downloaded from:

http://spybot.eon.net.au/
