When rebooting my computer or waking from sleep I get the message:
Device driver software was not successfully installed
Please consult with your device manufacturer for assistance getting this device installed
avast! Firewall NDIS Filter Miniport #245 Failed
Also sometimes I get an error box just like that except no software or driver is listed, it is just blank where there should be a device name
I am following this thread after looking everywhere for a solution. I am up for a AIS renewal in March after a multi-year license was purchased and I really don’t want to go elsewhere.
i am getting the same message and it blocks my incoming emails !!!
When I turn off avast, my emails come through. not an ideal solution
Did you work out how to solve this???
I have deleted the offending “devices” in Windows Device Manager and rebooted a few times, including powering off my machine, and they have NOT returned.
I still have no explanation. I will be installation my same configuration into a VirtualBox guest machine to see if I can isolate what causes this. I will update this thread with any relevant information and results.
Go into Safe Mode (hit F8 repeatedly) and run the Avast Uninstall Tool. Uninstall ALL previous versions and products of Avast you had on this machine.
Reboot.
Install the newest version of Avast and reboot.
Get Internet access and add the license key for AIS online.
Update the Avast definitions.
Also check for malware on your machine with both Avast and Malwarebytes Antimalware (MBAM) http://www.malwarebytes.org/ to make sure we are not dealing with another issue. Thank you.
