automatic internet connexion

Bonjour.
When starting my computer (running under WXPsp2),avast!4.6 open automaticaly my adsl connexion to internet, when update (general) is not set to “manual”.
I think it will be possible to set avast!, so it asks updates to the server only if the internet connexion is opened.But I did not find how.
Thanks for help.

Eric, avast does not dial or disconnect from Internet. But if there is a permanent connection to the Internet and you set it on avast! Update (Connections) tab, then avast! will check for an update if you set it to Automatic or Ask.

avast checks if there is an available connection each 40 seconds. If there isn’t, wait more 40 seconds to check. Checking does not take more than one second and, of course, does not use the Internet band. If there is a connection, check for an update. If there is not any new file to download, wait 4 hours to start checking again. If there is an available update, start it and install it. Again, wait 4 hours to check the next time. Some of this settings could be configurated different, I posted the default values of the avast4.ini file.

Check you firewall logs to see what is connecting to the internet at the time you think it is avast! connecting, as Tech says avast doesn’t establish a connection, but checks for the existence of one and if connected will check for updates as per your update settings.
