Bonsoir gbinforme,
Au temps pour moi, je ne connais pas bien le comportement d'avast! avec une connexion ADSL. As-tu essayé, justement, de paramétrer une connexion 56 kbps, même si ce n'est pas le cas ? Cela ne devrait pas affecter le déroulement des mises à jour manuelles, mais stopper les tentatives de PING des serveurs officiels.
Extrait du fichier d'aide de la version 4.1.304 :
# How does the update service work?
At first, avast! tries to detect if the computer is connected to the Internet - it sends a packet to one of our servers and waits for reply. If the packet is received, avast! "knows" that the computer is connected and the update may begin. If there´s no reply to the packet sent, avast! will try to ping the server again every 40 seconds.
If the ping is successful, avast! connects to our server and checks if there´s new update available. If it is, avast! will download and install it. If not, avast! will wait for 4 hours and then tries to connect and check for updates again.
Shortly said: avast! detects the connection to Internet every 40 seconds and looks for new updates every 4 hours.
# Optimization for dial-up connections
If you use dial-up connection only, there´s another way how to detect if the computer is connected to the Internet or not. avast! can elicit the connection status from the modem status - so it will NOT ping our servers every 40 seconds. To set avast! this way, open the program Settings, select the page Update (Connections) and check the option I only connect to the Internet using a dial-up modem.
# Optimization for permanent connections
If your computer has a permanent connection to the Internet, you can let avast! know this fact so that it can bypass the connection checks. To do so, open the program Settings, select the page Update (Connections) and check the option My computer is permanently connected to the Internet.
