I have tried everything I can think of to get auto-update working again, seems to have stopped after either going on to a DSL connection or the latest 603 program, got them both about the same time so don’t know which
to blame, even an uninstall, download & install of Avast4 Home 4.6.603 / 0508.4 did not help.
My o/s - Windows ME - Zone Alarm - DSL connection.
Avast settings - Update (basic) - “automatic” selected on both virus database & program. (“Update now” does not work, just sits there) - Proxy server settings, “Direct connection” selected, (have tried “Auto detect”) - Update (connections) - “I only connect using dial-up” selected.
These 3 programs all have access in Zone Alarm -
Avast4\setup\avast.setup — Avast4\setup\setup.ovr — Avast4\ASHMAISV.EXE — would appreciate any help.
Try add/remove programs>avast antivirus and then repair in the dialog box while connected to the internet.
This might help 
Thanks for the reply scaa, sorry to say it didn’t help.
Have you tried disabling your Firewall for a while and then try? Also -if you are using XP- disable the windows firewall.
yes I have tried turning off the firewall Spyros, and no I have Windows ME
Hmmm, something more drastic then? Why don’t you uninstall ZA, clean the registry, reboot and then try again? 99% of that sort of trouble comes from the firewalls…
