I've got an acer laptop with windows vista and when i switch it on, the windows firewall isn't switched on so i have to manually switch it on which is fine but i am having to do this each time i turn on the laptop and its driving me mad- how do i make it STAY switched on??
Trawling Google with this problem gives a number of different reasons as to why Windows Firewall won't stay on. Here is a typical one click here The most common reason if it is not related to Live One Care is that you have some malware that is causing it. Do a good sweep with Spybot, AdAware etc then follow the instructions in the link.
The full paid for version of avg has a firewall so that will disable your vista firewall.As for adaware you could still use that as an on demand scanner if you wish,that will not affect the firewall atall.When you install any 3rd party firewall(comodo,kerio)or in your case avg with built in firewall it deactivates the windows firewall as it will conflict with it.
