... I probably rebooted a half dozen times.
Just a reminder to all, re-boot means do a "Restart" not just a "Shutdown" followed by a start-up.

@  omarquo & lackschuh

Have both of you tried IDF's resolution in Reply #12, not that far above your posts ?

EDIT: Information from an Avast Team member in another topic.
Has the problem with the Firewall been addressed in this version?
The forum is loaded with reports of Firewall issues. Thanks

Hi Bob, if you mean the two problems with Firewall, one related to RDP and one related to its starting as a component, then both of the issues are resolved via microupdate in 20.2 and also we doublechecked it is resolved in this 20.3 BETA version as well. If you refer to different FW problems, please let us know more information. Thank you and have a nice day!

Try restarting your systems, that should trigger the Micro Update and or action it after the restart.

Not working! Remove and reinstall firewall component. After start windows from hibernate network is blocked.

It needs to be a full Restart to ensure everything is closed and the system turned off before restart as in the attached image. 

Is that what you meant ?

Did you also try what was suggested in this post https://forum.avast.com/index.php?topic=233304.msg1542398#msg1542398 ?

Can you also post your avast version number and build number as the micro updates should be reflected in the avast build number.

When my PC, for a very short time, can connect to my internet network on secure browser I can't open any website because "The firewall are blocking internet"; but on Firefox I can open some webistes... what a low level by Avast, very disappointed.

Way back in Reply #17 I asked:

<snip>

You didn't respond ?

Also in the interim period have you restarted your system, complete shutdown followed by a restart ?

This can have a number of effects:
For example, I have been waiting for a recent version number and build number update plus an update to the UI (user interface).  I got this today, version and build number and UI version number in my signature below my posts.
Are yours the same as mine ?

Also , Have you set your firewall to "auto decision" rather than "ask" (already waiting a fix for this issue)?
I noticed that when it was set to "ask", the internet connection or browsers was sometimes blocked.
svchost needs to be allowed , and this is not always requested or requested late.

I can't follow you.

What is "my internet network"?
What is "secure browser"?

What do you mean you "can connect" to my internet network .... I can't open any website?" You can? You cannot?

Is "my internet network" an intranet on the home side of your router?

Can you clarify any of this?

but on Firefox I can open some webistes... what a low level by Avast, very disappointed.


You say Firefox works to some extent. If Firefox is able to access the Internet at all, then Avast is not completely blocking the Internet.

It sounds like you may have different rules set up that are allowing Firefox but blocking your "secure browser" whatever that is.

I don't think he has responded.

Other things can be tried:

1) Right click the Avast icon, and try Avast Shield Controls > Disable for 10 minutes.

Then see if it works during those 10 minutes.

I don't know if this is supposed to disable the firewall, but it's worth a try to see if this helps.

2) Save your preferences, then uninstall Avast

a) Menu > Settings > Troubleshooting > Back up settings
b) Uninstall Avast, restart your system

See if it works

c) Re-install Avast

See if it still works

d) Then restore your settings: Menu > Settings > Troubleshooting > Restore Settings

See if it still works

Also, if some things are blocked and some things are not blocked, then you might be able to access the firewall logs to learn more.

Sleep or hibernate states won't help anything because Windows simply freezes in place and then resumes from the same state.

What do you mean "I also have to allow or disallow every rule again..." After you modify your rules, does the firewall start to work properly?

If that is the case, then it sounds like your problem may be that Avast is not retaining rules. Or - perhaps Avast is re-ordering your rules putting Block rules on top.

That is what happened to me - after getting the Firewall component added back, and entering my application rules, Avast kept messing up the application rule order, always forcing Block rules to the top.

I kept trying to re-order them using Move Up and Move Down, and guess I eventually got lucky with it, as they finally stayed in the right order. Once they were in the right order, things worked properly for me.

(But I was only able to get that far by removing and then adding back the Firewall component - until then, I wasn't able to even access the rules. So - I had two problems. At first a complete breakdown of the Firewall, and after resolving that, the problems with how Avast manages rule ordering.)

With secure browser I mean the Avast secure browser, with which I cannot open any pages because the firewall are blocking this browser.
I don't want ti use any other browser (I have Firefox for "emergency")

I tried everything but nothing chaned, I forced updates on Avast security premium but nothing seems to help.

I think it's time to change software, I am tired of all those troubles... it's not possibile to have all these problems with every updates, beacuse we have to pay (and it's not too cheap) to use avast.

I also use the Secure Browser and the Avast Firewall and have no problems.
You state you've tried everything which unfortunately from our end doesn't tell us much.
We aren't in front of or controlling your computer so everything for us means nothing.
For basics, here are the steps to follow:

Repair Avast:
Open the Avast User Interface > Menu > Settings > Troubleshooting > Repair App. > Restart the Computer or,
Control Panel> Program and Features (Add/remove program)>Select Avast> Select Repair. Reboot when completed
https://www.avast.com/faq.php?article=AVKB204

If Repair doesn't fix the problem, try the following:
If your Avast settings are not the default settings and you want them restored after the Clean Install, follow this before removing Avast.
