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";
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.
Way back in Reply #17 I asked:
@ omarquo & lackschuh
Have both of you tried IDF's resolution in Reply #12, not that far above your posts ?

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 ?
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.
