Avast free not installing on Windows 10

[mikeav73]

I just tried the latest offline installer and it is still having the no definitions updates issue.  Is there some other program that I can run to see what network it is trying to connect to?

Hello, I use this little free program to see in real time where the pc is trying to connect to

Hope this helps!

Well I used that program and the avast updater is trying to connect to a IP address of 0.0.0.0 on different UDP ports (I suspect it switching between ipv4 and ipv6 protocols).  No other info is displayed about the program and I don't know what to do from here.

Hi,

Have you tried disabling IPv6 in the network adapter's settings?

[jvidal]

did you check your hosts file? maybe some malware is redirecting the avast servers to 0.0.0.0

I tried disabling ipv6 and that made no difference.  My host file is clean as far as I can tell and the installer has the same issue on a fresh install of Win 10.  My modem has very few settings for UDP ports as far as I can tell.  I is a T220H Actiontec Telus modem.

Here is the firewall settings that it has:

Well I finally  figured it out, for some reason this setting IPSEC    VPN Service    50, 51-500 UDP in the firewall has to be enabled to allow updates to work but only under windows 10.  Got any idea why that is?
