avast Firewall NDIS filter driver blocks internet

[DrL2]

My internet is blocked unless I go into the Local Area Connection Properties and uncheck the avast!Firewall NDIS Filter Driver.  Is this a bug in Avast?  I am using the most updated program version 6.0.1367 and virus definitions 120129-0.

Which was your previous firewall? (before AIS).

It was the windows 7 firewall.  I have had Avast on this pc for 6 months with no problem until recently.

Suggestion: re-enable the driver, reboot, repair avast (using "Add/Remove Programs"), reboot.

Is the rest of avast working correctly?

Please report back.

Also, you can try an installation from scratch:

1. Download the latest version of avast! Uninstall Utility and save it.
2. Download the latest avast! version and save it.
3. Uninstall avast from Control Panel (if possible). If, for any reason, you can't run it, try booting in Safe Mode and doing it from there. Anyway, boot after that.
4. Run the avast! Uninstall Utility saved on 1 in Safe Mode. Boot after you've run it. Repeat this for any major avast! version you have ever installed/upgraded in your computer.
5. Install avast! using the setup saved on 2. Boot.
6. Register your free copy or add the license key for Pro. Or even upgrade your key from old versions.
7. Check and post the results. If, for any reason, you did not solve, try doing the step 3 in Safe Mode anyway.

Hey Guys, thanks for your suggestions, I tried the repair and that didn't work.  Before I did the re-install I checked the firewall and I found somehow the Network Location setting was turned off. I don't remember doing that, unless I clicked yes on some popup message.  Anyhow now all is fine.  Thanks for all your help!
