[Solved] Unable to start firewall!

My avast firewall won’t start. I’m using Avast Internet Security 2014.9.0.2008. I’ve tried a repair install multiple times, i’ve re-installed (using avastclear.exe to remove the previous files) and nothing has helped :(.

I’m running Windows 7 Ultimate 64-bit service pack 1.
I have tried disabling the windows firewall and nothing appears to be helping.

Any suggestions would be great!
Thank you.

is this a new avast install?
was your previous used AV fully removed. http://www.avast.com/faq.php?article=AVKB11

have you tried latest beta version. http://forum.avast.com/index.php?topic=142550.0

Initially i was using Free avast which i upgraded, but ended up reinstalling numerous times to try and sort this firewall issue.
Ive only ever used Avast, so yes.
I haven’t tried the latest beta version, maybe i should give that a shot xD.

Thanks for the fast response, i appropriate it.

Should i completely remove my current install and try the beta?

Should i completely remove my current install and try the beta?
read that topic and see what others did....

I installed the beta, after using avastclear.exe to remove my old install, and my firewall still wont start.

I had a read through the topic you sent, however no one really seemed to have issues like me :frowning:

Can we safely assume you’ve rebooted the pc after installing? The firewall service and other shield services only get started upon a new boot.

Yeh, i restarted after uninstalling and after installing.

I’d try a clean install with the online installer, it’s fixed alot of issues with people…

  1. Download Avastclear, Rejzors uninstall tool and the appropriate Avast program edition

Note : You need to be ONLINE during the install (sometimes online installer works whereas offline doesn’t)

Avastclear : http://files.avast.com/iavs9x/avastclear.exe
Rejzors Uninstall tool: http://rejzor.wordpress.com/avast-cleanup-tool/

  1. Uninstall Avast by control panel [If you don’t have Avast in control Panel go to #4]
  2. Uninstall in safe mode using Avastclear.
  3. Run Rejzors Uninstall Utility in Normal Mode (removes traces avastclear doesn’t) - reboot.
  4. Install the version you downloaded.
  5. Reboot.

Ok, so I did all that - issue still remains :frowning:

I found in safe mode that i couldn’t use avastclear.exe as there was no install folder after running the uninstaller from ‘Uninstall a program’ in control panel.

Avast says ‘Attentions Firewall is off: Turn on’. When i turn it on i get told ‘Unable to start firewall’. Ive tried turning the windows firewall on and off with no progress.

… I think I know what the issue is. In Device Manager… do you have a “corrupt” Avast Firewall NDIS driver?

I don’t see anything in device manager relating to avast. There nothing with an error (yellow exclamation). I gather this would be under Network adapters, of which i have nothing regarding avast.

Device Manager>View>Show hidden devices>Look in Network adapters AND Plug and play drivers

Okay, so I did that and found that there was no ‘Plug and Play’ category. However there was a ‘Non-Plug and play drivers’ category which had a few avast related devices in their. Under network adapters there was nothing avast related. Nothing in device manager has problems with the drivers (exclamation mark).

Ive captured both images on gyazo.

Remove the current version of Avast and download the latest from here http://forum.avast.com/index.php?topic=142550.0 this release has resolved a lot of firewall issues

I have already tried the beta version of avast, with no luck.

Just to be clear here, you did use the online installer I linked? Did you run it from the Desktop and as admin?

I didn’t run it from my desktop, but I ran the one you sent and as admin, yes.

Meh, I’m out of ideas here. The last thing I would suggest is running it from the Desktop as admin.

I’ll give it a shot xD

No, it still seems to be not working. Firewall just doesn’t want to start >:(
