This happens every time the computer boots up. If I wait until avast updates itself and do nothing else with the computer the above message appears and avast shuts down. I have the Home edition, and a Dell with windows XP.
I’ll appreciate any suggestions!
Thank you.

Try a repair of avast.
How to do it is explained in many thread on this forum.
Didn’t help but thanks! Think it’s a Dell problem but haven’t found any way to ask them or find a driver update or computer update.
Have you tried … a complete un-install of Avast, reboot, install avast again, reboot?
Welcome to the forums, toaf! 
Yes, I tried a fresh Avast and the reboot. This problem exists on my 04 Dell but not my 05. The 05 Dell is protected by Avast, how can I also get the same protection for the 04?
Check the folder \Data\Log
Are there any unpXXXXX files (X = some numbers) or files with .mdmp extension there?
