Done!
Works now for 35 minutes after reboot done for finalizing instalation. Before reboot I've patched aswTdi.sys with a new file. No BSOD, no change, no strange behavior - all seems to be OK.
Or maybe not all OK. You said that it will try to revert this file to original and ask to reboot, which I should not do. Nothing happent like that. I'm monitoring C:\WINDOWS\system32\drivers on my XP HE SP2 for all 35 minutes and the file was not change - so the reboot was not called to be necessary. Strange. I did NOT change anything in avast! It runs like it was installed.
The file was not reverted so it is safe (in my opinion) to reboot / turn off computer and using this new (4.5) _patched_ version as it should not crash the system after next run. If it does, I will report you.
Is there anything else you want me to do?
Regards!
