Hello

I've got exactly the same problem on Windows 7 (32Bit) and Avast Premium Security 20.4.2410 (Build 20.4.5312.580), Firewall set on private, no VPN activated. The problem occurred yesterday. The only way to write this reply was to deactivate the Avast Firewall. To have a minimal protection I turned on the Windows Firewall which previously was turned off. No as well the connection with the Internet as with my private network work fine. But of course this is definitely not the solution of this unbearable  issue. Hope that Avast reads all these posts and solve the problem as soon as possible.

Same problem here, no VPN, windows 7 Professional, all updates.  Avast installed the new update yesterday, I rebooted my computer this morning, problem happened after reboot.  Same symptoms everybody else is having, turning off the firewall allows everything to work.  Of course then you don't have a firewall.

In my case no, just Avast.  Which was working correctly until the reboot from the update.  I have tried a repair, it didn't help.

1. Download Avast Premium Security: https://files.avast.com/iavs9x/avast_premium_security_setup_offline.exe
2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions..!!)
3. Reinstall Avast with the downloaded installer from point 1.
4. Reboot.

Thanks, this worked. Not too happy that I spent an entire day trying to figure out that it was the Avast Firewall that was stopping the internet from working (also stumped my programmer friend). I think either an email should have been sent out to potentially affected users or somehow force out an update, if that's possible with the lack of connectivity. At least it's resolved now (for me) - I imagine plenty of others are struggling with this still!
