Update to the latest version (10.3.2225): https://forum.avast.com/index.php?topic=173591.0

I’m now on 10.3.2225 and the problem still exists.

Asyn · 2015-07-29T07:47:53.000Z

Which Avast…? (Free/Pro/IS/Premier)
OS…? (32/64 Bit…? - which SP…?)
Other security related software installed…?
Which AV(s) did you use before Avast…?

system · 2015-07-29T07:50:57.000Z

Free Antivirus 2015
Windows 7 Professional SP1 x64 + all windows updates
Didn’t had any AV earlier, and deactivated security essentials real time protection immediately after installing avast

First, be sure to get rid of all remnants of your prior installed AV(s)…!!
→ https://www.avast.com/faq.php?article=AVKB11#artTitle

Then:

Download Avast Free Antivirus: https://files.avast.com/iavs9x/avast_free_antivirus_setup.exe
Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions…!!)
Reinstall Avast with the downloaded installer from point 1.
Reboot.

Followed your instructions, but the problem persists.

To check I just went to https://chess24.com/en/watch/live-tournaments and the loader stays forever. Deactivating the web protection and it is working fine.

Asyn · 2015-07-29T08:04:18.000Z

OK, does it work if you disable HTTPS-Scanning…?

system · 2015-07-29T08:07:59.000Z

Yes, then the link is working…

I heard already from other users that they had this problems since ~1 week when using avast and want to browse chess24.com.

Asyn · 2015-07-29T08:10:37.000Z

OK, wait for one of the devs, this might be a bug.

system · 2015-08-03T18:42:18.000Z

Any news on this issue ?
This seems to be a very big problem on our website.

Hi,

you are the owner of https://chess24.com/en/watch/live-tournaments ?

We should fix this soon.

Just to let you know our users have exactly the same issues on our sites using websockets, including www.ludicash.com .

system · 2015-08-10T11:31:24.000Z

we have the same problem at www.sharelatex.com

avast don’t seem to be fixing the issue.

MartinZ · 2015-08-10T12:42:07.000Z

Hi gyus,

we are aware of the issue and working on the fix. It will be released in next few days.

system · 2015-08-23T12:45:43.000Z

Still now news ?
Will be forced to tell our customers to uninstall avast to use our website ? This seems a little extreme but we do not have much choice

Until the fix is available simply disable HTTPS scanning in the Avast settings:

This solution doesn’t work. Avast is also blocking non-secure websockets.
You need to disable the entire webschield to fix it.

Disabling Webshield isn’t a fix. Doing so puts your system at risk.
Maybe you need to start your own topic and describe your problem in detail so you can get some help.

Hi guys,

the patch has been released. Can you please verify it?

Thanks
Martin
