How do I know if my firewall is working?

Avast Free Antivirus / Premium Security

As the subject header states, so how do I know if my avast firewall is working?

I’m a previous owner of Norton 360, when Norton firewall is active, it disables the Windows Firewall. So does avast do the same?

2

Look to see what is happening in the firewall logs.

Check in Control Panel > Windows Firewall to see if firewall is on or off.

3

I checked, however Windows Firewall is turned on.

The windows firewall works alongside of avasts firewall but you can disable it if you wish to save some resources.

5

If you are using avast v2014 you should disable the Windows firewall.

6

So which one is better? To leave Windows firewall on or off?

7

If running avast! firewall v9, turn off Windows Firewall.
