no se actualiza la base ni el programa

Hola a todos y gracias anticipadas:
Hace unos dias que avast no tiene acceso a los servidores de actualización, desinstalé la versión 5 e instalé la 6.0.1000 he pasado la herramienta de desinstalación de avast y he vuelto a repetir el proceso con el 6 volviendolo a reinstalar. Hace unos dias que uso un nuevo modem-router wifi de ono pero creo que al principio de tenerlo si que se actualizaba. No se que hacer, alguna idea? Gracias.

Please, upload (attach) the avast log: C:\Program Files\Alwil Software\Avast5\Setup\setup.log
(or the shorter C:\Users\All Users\Alwil Software\Avast5\log\Setup.log).

If the file is too big for the forum, post the last 400-500 lines of it.

Thank you

The infamous 0x20000004 error…
Well, can you try into avast redirection settings to set “no proxy” instead of “automatic detection” and try?

I did it, no way

Which firewall do you use? Any other security program that could interfere?
Cual es tu cortafuegos? Algún otro programa de seguridad que pueda interferir?

I always used comodo with avast and I never had any problem

Remove the avast entries on Comodo programs list.
Boot and allow avast to connect again.

Ok I think comodo is the problem. When a turn off this firewall avast works correctly,but I always have both programs. Anyway thank you Tech.

Turning off the Defense+ in comodo all works perfectly.

Set Defense+ to a manual mode and allow avast requirements.
Maybe you need to purge avast entries from Defense+ first.
