I have windows98fe with the free edition of Zone Alarm and AVG also loaded.  Sometimes 
on initial booting I found that after the Zone alarm screen was displayed the mouse 
cursor 'froze'  and when I tried to move it the system did an immediate reboot.  
I also have 'cabrest' (registry restore program) so I did a registry restore at a 
date prior to the zone alarm problem.  This seemed to fix the zone alarm problem 
but I then found that when I clicked on the 'start' button I got the message 'Explorer 
has caused an invalid page fault in module unknown' also the start button menu looked 
really weird (large and small icons and lines).  Also most of the icons in the task 
bar disappeared.  On rebooting every thing is fine until I click on the start button 
which just then repeats the problem outlined above.  I have done virus checks with 
both Spybot and AVG which both report nothing in the way of a virus.  Has anybody 
any idea what I can try next?

Regards
Mike
