Hi all, I have installed Avast Internet security and since three days ago it shows a message “firewall noty active”; when I push the button “activate” it shows a message “cannot activate firewall”. I have made a complete scanning of my PC (Windows Xp SP3 installed with Windows firewall active)) but there are no viruses inside. I have written to Avast but no answer from them. How can I resolve this problem? thanks for collaboration.

Is any previous used AV removed using that vendors removal tool?
Have you tried avast repair?
Control panel > ad/remove programs > avast > Uninstall / change > repair option
Sounds like you are using a old(er) version of avast.
The problem with the firewall not starting has been fixed.
Perform a clean installation of the latest version:
