updates

Can u help. Recently I have been getting error messages because Avast has been unable to complete automatic updates. The message read “other HTTP eror (404) while trying 67.15.0.90:80/iavs4x/vpsm-53302.vpm” Does this mean all my updates will fail or is this a temporary glich? It updated OK a couple of days ago. JF ???

Where are you seeing this error message?
Are you realy referring to automatical updates or, on contrary, to manual started ones?
Which firewall do you use?
