Thanks, spreading the news. :slight_smile:

The download for Free: -https://files.avast.com/iavs9x/avast_free_antivirus_setup_offline.exe triggers Firefox’s not HTTPS connection on the redirect to the actual download as it is an http connection. See attached image.

Not great impression for a Security Based company, I reported this on the last program update but it is still the same.

Thanks for the new release :slight_smile:

Yeah… That’s strange why all the offline files are provided via HTTP.

Is there a download link for Avast One? Thanks.

thanks for this release , installed it this morning ( avast one ) update went smooth , but opening the gui and loading it fully takes some time and the " white screen " is there , just like the other avast products.

Hi, After the update 21.9 the firewall icon has completely disappeared on free avast. The antivirus tells me it’s not install. on adding components the firewall option is missing …

• One Essential: https://files.avast.com/iavs9x/avast_one_essential_setup_online.exe
• One Individual: https://files.avast.com/iavs9x/avast_one_setup_online.exe

where the firewall feature for free users hasn’t appeared even though it says it’s available at the end of October
while I’m already using the latest UI, don’t tell me that the firewall is still locked for general users overall ? >:(

it was already the case last week when I wanted to download version 21.8… It’s a bit strange as security for a link from a company like avast

Hi, no idea why it got removed from your system. Anyway, if you need it urgently, you could switch to beta-channel, it should be available there.

Edit: How did you update to 21.9…?


hi, from the parameters update the program

Please pardon me but I can’t find the place to post that since the update this morning I am not able to load one of my games in my Brave browser. I think I know what I did…I chose “yes” on an option but I have no idea how to get back there…it was while addressing the "Global Privacy"options.

I really need the help or if not here can you please point me in the right direction?

Your time and consideration will be appreciated. :slight_smile:

After installing it on Windows 10 laptop Youtube started bombarding me with ads even though I have AdGuard browser extension ad blocker in Firefox. This never happened before, like it somehow made adblocker ineffective. Hm.

I want to ask for certainty about when the firewall feature is by default in avast free without the need to be a beta user, because it is scheduled for the end of October all users can use it or will it be given at the end of this year ?

Beats me, wait for one of the devs…

I hope that the new firewall feature will not be turned on without explicit action by the user. I support distant non-tech users and may not be able to reach all of them if the firewall suddenly springs to life.

The Free Firewall needs to have the ability to let users manually add programs into it to create rules. Otherwise, it would be worse than Windows Firewall. The last time I checked the free firewall, it didn’t have the option. Hopefully in the final version we’ll have it.

Hi, I can’t comment on AdGuard, but (JFTR) no issues witch uBlock Origin here.
