Hi there.
First of all, let me say that I'm normally a very happy user of the free version of Avast. Lately though, I've been noticing some strange things.
I like to watch streams on twitch.tv, and I often watch videos on the internet. The webshield though, seems to be blocking this, well some of it. I cant watch Twitch.tv without it making it reloading the stream constantly. I can without problems watch YouTube videoes and stuff like that, but I cant watch the videoes on my local news site.
Everything works perfectly, as soon as I disable the Webshield. I'm using Windows 8.1 and Google Chrome.
Can you help me?
Thanks.

It's possible these blocks are legitimate and are now detected because you are now running Avast! 2014, whereas version 8.0 was not able to detect or see these threats.
Maybe something one might think about a bit before disabling WebShield?
Links to these sites are welcome, and I will investigate each of them for possible site malware for you.
If you post a link, please make them as hxxp:// and not http:// so they are not a live connective link for unaware users to prevent any possible infection to them. Doing it this way will prevent any possible harm coming to other users here.
Screenshots of the warning pop-ups will help also.
-
Many streaming sources though using http ports, don't strictly use HTTP protocol, this can mess up the web shield as it is expecting HTTP protocol.
Is there a particular area of twitch.tv that you have problems with ?
I just checked access and was watching the 24hr Battlefield Stream for a while without any issue.

hxxp://www.twitch.tv and hxxp://www.ekstrabladet.dk
I do NOT get any warning pop-ups. On ekstrabladet.dk - it just shows a black screen where the video should be. On Twitch.tv - it just keeps reloading the stream. Shows the stream for 3 seconds or so, and reloads again. No warnings whatsoever.

Its every single stream on Twitch.tv
If it helps anyone, then I can record a video of what happens?
-
I just tried 3 videos on twitch.tv and was able to watch them for over 10 minutes each without a problem and webshield on.

I dont know what to tell you.. I just know that, as soon as I disable the Webshield, it starts working.

Whilst this might seem strange as it doesn't relate to the web shield, I just wonder if it could have an effect.
With the web shield enabled - Try disabling the 'avast! online security' plugin in Chrome and see if that makes a difference.
Sorry I can't tell you where to do this in Chrome as I don't use it.
-
Chrome...click on the three bars>click "tools">click "extensions" :)
-
Thanks Para-Noid.
Whilst you are here, you could try connecting to the twitch.tv site and see if the streams are working for you with Chrome, Web Shield and 'avast! online security' enabled. I suspect that there may be more to this than the Chrome, Web Shield and 'avast! online security' combo.
-
That dosent help unfortunately. I've tried that already. And at the moment, its not even installed, the Chrome plugin.
-
Both wXw.twitch and wXw.ekstrabladet come out as clean at the moment.

Possible iffy add-ons or rogue toolbars present in your browsers? Browsers clean? Neither DavidR or Eddy are reporting issues.
Only thing showing is a redirection for ekstrabladet in zulu and a minor elevation in risk in zulu Netblock size. Otherwise everything looks normal from here.

twitch.tv works great here! Chrome w/AOS enabled and Firefox w/AOS enabled.
As far as the web shield goes I never disable it. All shields up and always running.
Sorry it took so long to get back to this thread.

Had to register to come and announce I have the exact same problem.
All twitch streams reload every few minutes for me. Downloading certain (100% trusted and legit) files stop downloading completely, I have to pause and resume the downloads to get them to start again.
Everything works 100% perfectly without webshield.
Using Firefox v24 on Windows 7 Home x64 (tested all this stuff without the online security plugin, no effect. Only Avast WebShield makes everything reload).

Update Firefox to v25 fixes this issue

Its really really weird, that it works fine for you guys.
I've tried to disable every addon I got. AddBlock, Evernote and Tampermoney. That dosent help, until I disable the Webshield through Avast. I dont even have the Chrome avast addon installed..

hi Bugses,
Are your browsers really clean? Any unusual behavior in any of them? avast! could be detecting something in your browser(s). Reason I say that is because I've no problem and neither does DavidR or Eddy, and pretty sure we each take the time to ensure our browsers are clean and operating the way they should.
I also make it a point to never disable real-time protection just to visit a favorite site just because it gets blocked, so.... I investigate the site itself to see if there are, in fact, reasons why blocks/di(s)connects are happening and then notify the site owner of such if the blocks are true and valid. Might also want to try a clean, fresh install of adobe first, to see if that is really your issue.
You can get the full install version here: http://www.adobe.com/products/flashplayer/distribution3.html (http://www.adobe.com/products/flashplayer/distribution3.html) Uninstall/reboot, then install new/reboot. MSI installer works best, imo.
-
I have this exact issue as well.
Windows 8.1 - Happens in all Browsers, my Firefox is updated to 25.0. - flash is the latest version as well.
Streams keeps reloading every few seconds, I'm lucky to be able to see 10 secs.
Looking at the taskbar in windows the avast logo is "turning" all the time, pretty sure it shouldn't do that.
(also the captions here are really annoying)
-
The fact that the avast tray icon is rotating is because it is scanning and streaming content is likely to do that. If it reloads, then the process would start over.

Hi,
I am having the same problems after updated to Avast 2014. Everything was normal, now i can not watch twitch tv streaming anymore.
My info: Windows 8, Avast 2014 (lastest program and virus definitions), up-to-date Chrome.
Problems: Twitch tv streaming video keeps refreshing every 5s (the Avast icon turns constantly), everything else is normal (webpage, youtube, etc), no warnings.
Some did not work efforts: Disable Avast extentions in Chrome, disable Reputation services, clean up Browser.
I tried disable Web shield and it's good though .... Very frustrating cause it was totally normal before i updated to Avast 2014 >"<. Now i have to Right click Avast icon -> Disable all shield -> Open Chrome and Twitch -> Enable shield again.
Hope there will be solution soon.
Regards,
-

What do you consider the "latest program"? Perhaps it might be better if you actually specified the programme, as in AIS (Avast Internet Security) 2014 v. 9.0.2007 (which is the latest programme, update issued on Oct. 31, and which fixed my network streaming issues). With accurate data (including for Windows) it is much easier to help. Sucha s:
My info: Windows 7 Ultimate x64 SP1, AIS 2014 v. 9.0.2007, no other security apps installed or running

Well, I am trying to update Avast frequently these days hoping it will fix the problem. So it is 2014.9.0.2007, but does not fix it.
Also i'm using Windows 8 x64 with Windows Firewall enable. But this should not be the problem because it was normal until i updated to Avast 2014.
Regards,
-
I have the same problem. Running Avast Free 2014.9.0.2007 on Windows 8.1 x64 with all updates, Windows Firewall and no other security software installed. In Firefox 25 all Twitch.tv streams refresh at short random intervals (usually every few seconds, sometimes after 20-30 seconds). Using Safe Mode, disabling addons or setting http://*.twitch.tv/* to the exclusions list in Web Shield do nothing to alleviate the issue, the only solution so far is completely disabling the Web Shield. The same streams work, however, in Internet Explorer with Web Shield up.
-
That would tend to suggest it is a Firefox problem if IE is functioning normally
-
I have the exact same problem as the users listed above. Having web shields enabled in Avast blocks most web streams and large image files.
System details:
Win 8 x64 - standard with no goofy software installed.
Before you parrot all the 'experts' above:
No other security software installed. Problem occurs in ALL browsers (Chrome, FF, IE) regardless of extensions. ALL are up to date to the latest version. No, there is no problem with my browsers being compromised. Weekly scans with malwarebytes, adblock (and noscript on FF) always running, and no I don't visit sites that would be delivering malware.
BROWSERS CLEANED, PURGED AND RE-INSTALLED
AVAST RE-INSTALLED x3
Both my girlfriend and I are coming up on our yearly PAID FOR avast subscription. Unless I can see a fix for this it's back to Norton instead. The only solution so far is to entirely disable Web Shields. No point in paying for security software if it won't let me browse the internet as usual. >:(
-
Oh, and all this started with the update to the 2014 version. There was no issue before.

Hallo, we have discovered an issue in new WebShield implementation. This is probably reason of your problems. We are preparing fix for that.
Meanwhile you can try to switch to old WebShield implementation. To do that, please
Go to C:\programdata\avast software\avast directory
Find the WebShield.ini, file and add following lines:
[General]
UseStreamFilter=0
Now restart „avast! Antivirus“ service, or reboot.
Please let us to know if the problem is gone.
You may need to disable Avast Self Defense temporarily through Avast>Settings>Troubleshooting

If you use notepad.exe for the edit, the only text editor allowed by the self-defence to edit the .ini files, you shouldn't need to disable the self-defence module. When you save the edit you will have to acknowledge the changes (self-defence at work), just answer Yes.
The only other issue is that from win7 onwards, windows 'may' give an access denied error, if so it may require that you run notepad.exe as administrator in order to make the changes.

I have the same problem on Firefox with the sites using Flash Player, since I have updated Avast from V 2013.8.0.1504 to 2014.9.0.2011. All was Ok before.
I will try later (I am not at home) the WebShield.ini change from Alikhan/Zdenek
System : Win 7 home french, Firefox V 26, Flash Player V 11.9.900.170
what I am sure, is that I will wait before updating Avast (from V8 to V9) on my other PCs.
NB : What is strange is that the V8 version I had (V 2013.8.0.1504) is not refrenced in the "Avast Release History" (see www.avast.com/fr-fr/release-history?utm_source=prg_fav_80_0&utm_medium=prg_lnk&utm_campaign=free2paid&utm_content=prg_fav_fr-frupdate_info-link&p_var=.%2Ffa%2Ffr-fr%2Fupdate_info-link&p_elm=66&p_lex=198&p_lid=fr-fr&p_lng=fr&p_lqa=0&p_lqe=0&p_lst=0&p_lsu=24&p_pro=0&p_bld=empty&p_vep=8&p_ves=0&p_vbd=1489&p_hid=e161cef0-bed9-49c4-adf9-0a27f0819f10)

8.0.1504 was probably a beta which is why it's not listed under the releases.
-
But this version was installed by the Avast normal update process, and i though that this process only installs "steady" version, not beta version.
On a PC with Vista, and Avast free, french version 8.0.1489, the Avast update windows says that the last version available is 9.0.1504 (9, not 8), so not knowing the version that would be installed, I have kept this 8.0.1489 version.
More important, are the problems discussed in this post linked to the post "Fix for WebShield download issues" (hxxp://forum.avast.com/index.php?topic=143211.75) where Lukas (avast! team Super Poster) gives some interesting information ?
-
While the solution posted earlier does seem to work, I can't understand why this problem still persists in the latest version of Avast (how many months has this been an issue now?). For the record, I have this problem on all 3 of my computers using Firefox, IE, and Chrome. No videos will play at brietbart.com or 49ers.com (the only 2 examples I'd found until reading this thread), unless you disable WebShield or perform the temporary fix in the WebShield.ini file mentioned earlier.
This has got to be frustrating a lot of users who aren't aware of what's causing this problem. I've been dealing with it for months and finally went back to Avast 8 on one of my main PCs.
