Avast blocks Battlefield 3 join requests

See this thread for details:

Users of Battlefield 3 are having issues where Avast is blocking legit websocket connections. As a result we do not receive a join request to play with our friends. I can disable Avast! to work around this.

Avast info
Program version: 6.0.1289
Engine/virus definitions: 111025-1

In the Web Shield’s expert settings, there is a check box titled “Scan traffic from well known browser processes only”. Try to tick that on, see if you get results.

fyi, the link requires a login.

Hi,
Avast 6.0.1289
def: 111025-1

Basically, this is what’s in that page.

Test websocket connections in Chrome 1. Go to http://websocket.org/echo.html [websocket.org] 2. Click on Connect. Do you get a line saying CONNECTED in the Log window? 3. Click on Send. Do you get SENT and RESPONSE lines in the Log window? 4. If you answered "No" to 2 or 3, check Use secure WebSocket (TLS) and try 2 and 3 again. Different result?

Please update your posts in this thread if you have Chrome installed and add your result from this test.

  • Could you connect with/without TLS?
  • Could you send messages with/without TLS?
  • Could you receive messages with/without TLS?

Tested Anti-virus programs so far (Updated continously):

LATEST version available and DEFAULT settings if not stated otherwise:

Avast
Works if web shield is disabled/stopped.
Also reported to work if you go into the settings and check the box “Scan known processes only”. Then everything else can be left on.

Ask Avast why they block legit websocket connections here:

For me, I do not get a response unless I disable webshield or use the TLS version.

Hope this can help? I don’t want to disable/stop webshield to play the game.

I tried what Gargamel said but it didn’t help…

Tried the above with no result.

Would like to report that I am having the same issue.
Running latest Avast with latest updates.

Disabling webshield, or enabling “Scan traffic from well known browser processes only” works.

A copy/paste from my Battlelog forum post about this issue:

–
Firefox 7.0.1

  • Adblock plus 1.3.10
  • Ant Video Downloader 2.4.4
  • Download Statusbar 0.9.10
  • IE tab 2 (FF 3.6+) 3.10.7.2
  • NoScript 2.1.7
    < disabling addons has no effect >

Avast! Free Antivirus 6.0.1289

  • virus definitions: 111030-0
    < is always updated >

Windows 7 firewall
< all windows 7 updates, including optional >

Router: Alcatel Speedtouch 510 (firmware 4.2.7.16.0)
< old router, with latest firmware >

I would like to report that adding battlelog.battlefield.com/, or any form of that. Has no effect on the issue, I cannot receive party invites and Battlelog doesn’t not auto refresh. Only solution at the moment is either disable webshield, or enable “Scan known processes only”.

I have the same issue. The shield log shows that it’s taking no action, but disabling the web shield resolves it for some reason.

Same problem here.

Very annoying.

As Dommelrbb mentioned there is a workaround:

Obviously the lessor of the two evils so that you retain web shield protection is Don’t disable the Web Shield, check the “Scan traffic from well known browser processes only” option in the avastUI, Real-Time Shields, Expert Settings, “Scan traffic from well known browser processes only.”
