Solved: Avast Update won't start - Firewall issue?

Post Re-edited.

I have been using Online-Armor for a firewall with Avast version 4.8.1299. Avast was installed before the firewall. It’s been fine.

The new Avast update won’t start up after a reboot unless I kill the firewall. The PC loads the firewall and then stops before the Avast icons come up. Killing Online Armor lets the PC finish booting and I get Avast.

I did a system restore to get back to the earlier version of Avast and the system worked again.
I then let the old Avast update and the same thing happened. I thought that uninstalling Avast and downloading the latest Avast issue might be a work-around. But when I did that, I guess I got the old version 4.8.1299.

Any suggestions? Maybe I should uninstall the firewall and reinstall it over the latest Avast.

Final Edit: The above worked.

OA has some issues with avast WebShield… and maybe this is a new problem now.
Did you set to delay avast services loading at startup under Program settings > Troubleshooting tab of settings?

Update:

I uninstalled Online Armor and let the Avast update happen. Computer booted OK. Then I turned off Avast, and reinstalled Online Armor. Online Armor goes into learning mode on a new install, so it accepted Avast. System boots.

Problem solved, I hope.

I also have Online Armor and have just updated the latest Avast prog. Before I did though, I put OA into ‘learning mode’, and the prog update went through with no hitches. I’ve had problems before when I haven’t used ‘learning mode’ which resulted in extremely long startups.
