First off the bat, I've scanned in both normal and safe-mode with avast and malwarebytes, and do not have anything.
Basically, ever since the update, Web Shield is absolutely killing my bandwidth. I can't watch a YouTube video for more than ten seconds without it having to buffer and after that, it won't even stream and of the rest of the video.
After loads of different testing I did on my own (different routers, noise margin test, speedtests, test sockets), I had the idea to turn off Web Shield to see if that was causing the problem. The problem was solved straight and I had my regular bandwidth back.
So basically, is anyone else getting this and what the hell is going on with Web Shield avast!

Which version of avast?
The latest is v2014.9.0.2011

What is your OS?
Any other security software?
Firewall?
-
What is your OS? - 7 ultimate 64 bit
Any other security software? - malwarebytes
Firewall? - Only Windows firewall on and that's not supposed to be a problem with avast! (I heard)

First off the bat, I've scanned in both normal and safe-mode with avast and malwarebytes, and do not have anything.
just some info ....
Malwarebytes is not designed for safemode scanning, safe mode should only be used if normal scan does not work
It will work in safe mode, but all drivers are not loaded and therfor crippled....
-
You are correct the windows firewall isn't an issue.
How did you update you avast, through the GUI or a clean install?
Have you tried a repair...Control Panel>Uninstall a Program>double click "avast">click "repair">reboot (it might take more than one reboot)

That's more than true, but I like to do both just to be sure. It always kept me out of trouble anyway :)

Did the repair, no such luck I'm afraid :(
I install updates through the UI yes.

Uninstalled, rebooted, cleared registry with CCleaner, installed avast again - still the same problem :/
I think I'm just going to disable Web Shield at this point. I know this solves the problem, so I see it as my only option at the moment. Hopefully this will be fixed in a future update. As I said before, I've scanned with both normal and safe mode with avast and malwarebytes and there's nothing. Clearly a very small problem that doesn't affect many people, but I'm unfortunately one of them :(

It sounds as if there is something else going on.
Be patient as a malware expert will catch up to you.
Sorry I couldn't help you more but there is definitely something
else going on.

It's not a malware problem.

Which previous security solutions did you have installed.?
Have you gone into computer management and then device manager and removed phantom network drivers.
This worked wonders for me.
-
You can try disabling new webshield (so it will be back to normal e.g old technology):
Go to C:\programdata\avast software\avast,
Find WebShield.ini, add the following lines:
[General]
UseStreamFilter=0
Restart PC. You may need to disable avast self defense (Settings - Troubleshooting).

None. I formatted Win 7 less than two weeks ago and I've only ever installed avast! and malwarebytes so a conflict of applications can't be a problem as I've run these two applications side by side for years without any problems.

As said before, disabling Web Shield works fine and it's back to normal. It's obviously some rare bug that some people have had (I've seen numerous other posts about Web Shield from other people saying the same thing). I'm just going to disable web shield until an update is rolled out and hopefully it works then.

This setting does not disable it, but "downgrades" it to previous technology (meaning local transparent proxy).

Oh, sorry dude, that sounds great then because before the update, I did not have the problem. Thanks dude, sorry for the misunderstanding.

I can't find a Webshield.ini file.
C:\Program Files\AVAST Software\Avast <---where i looked.
Any ideas? Can I just create one? Are there any other lines beside the UseStreamfilter?
-
Why alter a file? Doing this could cause other bigger problems.
If all else fails re-install a previous version. if you still have the installer.

It's Programdata, not Program files :)
Copy from above.

It's safe. Lukas shared this tip because of my issues and it worked.

Could you provide a link?
I've seen this issue with v2014.9.0.2011
A link would be very helpful.
I like to bookmark things, that way I don't spend all day doing a search.
edit: Thanks for stepping in to help. :)

Sorry, don't have link since it was via email :(
But, this should be last thing to do. I mean, after new release which hopefully fixes these things, it should be re-enabled. But as far as I know, it won't be done automatically. I might be wrong tho. Nothing bad, but still ;)

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 rollback to old WebShiled implementation. To do that, please
Go to C:\programdata\avast software\avast folder.
Find the WebShield.ini, file and add to this file following lines:
[General]
UseStreamFilter=0
Now restart „avast! Antivirus“ service, or reboot.
Please post here if disabling the Web Shiled solved your problem.
Thank you
This should do 8)
