I have exactely the same problem with my Windows XP home edition 
I had to use the tool âUninstallUtilityâ to remove the program.
then i :
. Boot.
. Install again the last version.
. Boot.
And it doesânt work.
I removed it again.
I start windows in safe mode to use âthe administratorâ account
and i install avast with this account and it doesânt work.
I tried many things but i have always the message :
ashAvast.exe - Erreur dâapplication
Lâapplication nâa pas rĂ©ussi Ă sâinitialiser correctement (0xc0000005) âŠ
Iâm French so i use a French version of XP 
In english : Application Error - The application failed to initialize properly (0xc0000005).
What can we do ???
???
Thanks
