i read this forum as much as i could but didn’t find the same problem that i’ve experiment .
when i try to update avast (either virus def. or software ) i got a popup from vista ( acknowlegment to continu ) and then …nothing! . It just stop , without any other infomation .
Someone already experiment that kind of thing ?
i’m pretty amazed…
Just tried it on my system - Right click the icon - select programme update… UAC appeared - clicked OK and it updated no problem… Next question what is your firewall and is the setup allowed to access the net ?
