I have recently installed sygate 5.5 firewall allowing avast to access internet. Perhaps something wrong with it? Do you have anything to suggest which I could check?
Most probably... If you manually ask for an update, Sygate should ask for all components access needed to update. Can you do so? If you have already done and answer yes to persist the authorization for connection, probably, you're get the pop-up window telling you have the last avast! version...
Do you use dial-up or DSL? Have you configured avast! connections settings properly?
Few minutes ago I received an automatic update (or, better, a push-update from Professional version):
New iAVS update (VPS 440-1) for avast! program has been released recently.
Related information could be also found on our Internet sites.
