Firewall Misconfiguration
« on: April 17, 2014, 09:21:04 PM »
Hello,

On Device Manager I have three "avast! Firewall NDIS Filter Miniport" (plus one Miniport #2, four total) with the following under Device status:

Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)

What shall I do to correct this issue, please?

Uninstall Avast, use the avastcleaner if it fails, do a little registry checking and Hidden devices uninstalling if need be.
After that reinstall Avast fresh.
OS's used: Windows 10 Pro (x64) 1607 <-> Windows 7 Ult (x64) <-> Windows 8.1 Ult (x64) <-> Windows 2012 Essentials R2 (x64)
Avast Internet Security (sub for 10 PC's), HPM.Alert, Malwarebytes, Asus-x99 Deluxe/U3.1 (Intel Core i7 X980 EE - 64Gb Ram - NVidia Geforce x980 - Samsung PCI-e 950Pro 512 SSD), Microsoft Surface Pro 4 (6th Gen Intel Core i7 CPU - 16Gb Ram - 512 SSD)
When installing Avast! be sure to use the custom install... never the default!

Are you sure? Because I have done that not long ago, as you can read on my last post on this thread:

A new version released today 9.0.2018.

It would have been better if you stayed on the same topic but since you already did one and it hasn't removed the 3 entries, you may have to do it manually.

You need to do a clean install because since v9, the firewall doesn't list any miniport drivers in device manager anymore.

You need to remove them 3 manually before installing avast by right click > uninstall through device manager if they are not removed after running both uninstallers.

On another note, are you sure your PC isn't infected? (that can cause problems with avast installing/not functioning)

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

Note: It's important you used the stub online installer from the one I linked.. NOT the offline one.

Note: You need to be ONLINE during this install (online installer works in all cases whereas offline sometimes doesn't)

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

2. Uninstall Avast by control panel  [If you don't have Avast in control Panel go to #4]
3. Uninstall in safe mode using Avastclear.
4. Run Rejzors Uninstall Utility in Normal Mode (removes traces avastclear doesn't) - reboot.
Check : Once uninstalled check in device manager>view>show hidden devices if there is anything related to avast with a yellow triangle.. if so, uninstall it and reboot.
5. Install the version you downloaded.
6. Reboot.

Note : If you have a paid license, install it after the reboot at stage 6.

I followed the steps on your post, but reading a part of it, it might not have been necessary because if the entry existed in Device Manager it was because the drivers where still there from an earlier version of Avast and because avastclear.exe and Rejzor's uninstall tool do not clean properly. After using them I still found many leftovers on the registry. They were all paths to *.dll files, so that not really important, but still there. I am almost sure that Revo uninstaller on Windows safe mode would not leave any left overs. Anyway, I had to clear it by hand. and the paths can be removed with a registry cleaner.

I started a new thread because it is a different subject, the other one was solved and it was already some time ago.

It seems solved, thank you very much for your help.

You're welcome.

Regarding the registry keys : As far as I'm aware some are left since there is a risk it could (possibly) corrupt the registry. Or a simple case that since avast! has released program updates quite fast in these past few weeks, these uninstallers haven't been updated.

I don't think either uninstall tool has permission to remove from device manager but it shouldn't have been there during the upgrade anywhere.

On another note, never, I repeat never use Revo for a security product removal.

It's good for normal applications but since security programs are installed at different levels one mistake could be fatal.

Each antivirus vendor have their own removal tools to your needs.
