The link you provided in your last post is 2 years old. A lot has changed in 2 years! That is why most of us here keep our software (and OS's) current because security holes are just more opportunity for malware, intruders, etc, to get into our system.
I use several different OS's including XP-Home and XP-Pro with Avast through the many different versions and beta versions. I've done uninstalls/clean installs and upgrades and never had a problem with a "crash" or BSOD on these OS's.
I think your best solution to your problem would be to:
1. Submit a mini-dump file to Avast to analyze, but you need to do this at the time you are actually having the problem:
- Here is additional information on how to invoke a memory dump file:

- Please, zip and upload the C:\Windows\Memory.dmp file to this anonymous ftp server and
name it uniquely:
ftp.avast.com/incoming. Avast will analyze it and respond back to you in this thread or to your email.
2. Update your OS to SP3, which you are reluctant to do despite discussing it with the Avast Evangelists who troubleshoot issues daily with users. I understand that this is your machine and you are entitled to make what ever decision you wish, but we are advising you to what is best for better security for your machine.
So you have choices on how to resolve your problem. It is now up to you to decide what to do.
