Hello,

by waiting about support answer , I noticed each time I boot my OS or each time I want to activate manualy web shield , I have a system event log error.
In french:

Type de l'événement :	Erreur
Source de l'événement :	Service Control Manager
ID de l'événement :	7000
.....
Le service Avast StreamFilter Driver n'a pas pu démarrer en raison de l'erreur : 
Ressources système insuffisantes pour terminer le service demandé. 

Traduct:

The Avast StreamFilter Driver service failed to start because of the error:
Insufficient system resources exist to complete the requested service.

As this message does not appear with avast 2015 v2218, it’s likely that this is the reson of my problem but I have now no idea how to resolve
My config on winxp = PIV 3.2Ghz Ram=2 x DDR2 1G PC3200
