Title: Upload Issues (Web Shield) [Fix inbound]
Post by: [Oli] on January 16, 2014, 10:58:34 PM
Dear Avast,

Since Version 2011 I have been experiencing issues with uploading files to dmcloud and sproutvideo. The uploaders would claim that my upload speed was 3gb/s when the actual speed is kb/s I have found disabling the Web Shield fixes the issue however I wanted to find a simple fix. I installed the new beta hoping this had been fixed only to find that the issue is still active.  I have installed a clean version of Windows and have gotten the same issues as before.

Problem:Uploading content to websites using flash and HTML5 uploaders results in the illusion of "ultra fast" speeds when the file is being actively skipped by Web Shield.
OS: Windows 7 64 Bit SP1
Clean Install?: Yes
Clean OS Install?: Yes
Avast Version: 9.0.9.2012
Troubleshooting: Disable Web Shield and attempt to upload file. File Uploads act normally. Reactivate Shield and uploads start to zoom up in gb/s rather than kb/s.
Installs: Installing from version 2011 to version 2012 caused the anti-spam module to disable it's self. Installing BETA 2012 on clean OS Install has fixed this problem however the web shield issue is still active.

 I have installed the latest BETA build and it has become even more unstable after doing a straight install over the previous version.


Should i do a clean install?

Thanks
Oliver

[update 1]: AVAST has offloaded some of the web shield resources onto the "cloud" causing a bottleneck when uploads happen. This was meant to improve performance and provide on-the-fly updates to the latest vulnerabilities  however people with slower uploads/connections are finding this problematic. Testing was done on a fast network at AVAST so this bug wasn't discovered until users started using the product. This has happened in the past with other Avast products and is just part and parcel of modern software development. It has been suggested that making the shield go into "proxy mode" ie without streaming updates should help provide a temp fix
[update 2]: I contacted Lukor to get an update on the progress of the bug, He provided me with an Alpha build which has fixed the issue. This should be passed down to everyone else thru a new software update however you will need to switch off of proxy mode to get the streaming mode back.
[update 3:Build 2013 has been released to everyone http://forum.avast.com/index.php?topic=145192.0;topicseen

Ive had to reformat the machine again, Since installing the beta the following issues have happened.

Flash Player (ActiveX) has removed its self from the uninstall list.
Web Shield crashes Avast after disabling the Web Shield during an upload.
Web Shield is currently causing the computer to provide inaccurate reading of the upload speed of the computer when uploading.
The Anti-spam module has been disabled since installing the beta version of avast. running a repair install has not helped resolve this issue.


OS:Win 7 64bit
Avast Version: 2012


In Version 2011 I also had issues with the Web Shield however I had the ability to disable the shield with less crashes. Since the beta update 2012 the computer has become unstable. I am very disappointed with the changes in Web Shield.

Ok Day 2 of problems (No Response from AVAST yet...)

Have installed a clean copy of windows and a clean copy of avast 2012 (Beta)

Have tried to upload a video to sproutvideo.com using the HTML5 uploader and have had the upload uploading at 6gb/s (which isnt correct) after disabling the web shield I am able to upload again without issues.  The same problem also happens with api.dmcloud.net and dmcloud.net's flash uploader. Disabling the Shield is the only way past this or finding an alternative piece of software until Avast can fix this. I have been using Avast since version 7 without problems. Now with Avast 9 there has been software updater issues and uploading problems.

Hi Criag, Ok thought that the Web Shield fix post would be the place to post feedback as lukor said "I would be very happy to hear about your experience with the patched driver.
" When i had this issue with 2011 I was informed it was related to that fault posted on the forum. Sorry if i caused any offense.
Title: Re: Upload Issues (Web Shield)
Post by: CraigB on January 17, 2014, 05:23:50 PM
There is not much I can offer you in explanations I'm afraid, I never had to use any patched driver and the beta functions perfectly for me.

I have reported this topic so hopefully the avast team will look into it for you.

Sorry, but I am really p*ssed off!

Since before Christmas I have problems with the new Avast!
First Dropbox synchronization was and is not possible anymore (upload)
and I hung up with that (also in the Dropbox-Support forums).

Now I habe seen, that it seems to be that generally uploads to websites
are difficult, because that doesn´t work either! With the same problems,
first ridiculous high speeds, but no uploading at all.

I tried repairing Avast, I tried the fix, I tried the beta, nothing helps.

Problem ist the web shield.
Next problem: Avast freezes most of the times, when I try to deactivate
the web shield!!! I event can´t kill the frozen Avast-task with the task monitor!

Then I have a jolly entertainment with rebooting my computer, waiting
for Avast, trying to deactivate the web shield again, freezin´, rebooting
my computer AGAIN and so on and on.

I use:
Windows 7 Home  SP 1, 64 bit
Avast Free, 22014.9.0.2012, Version 140114-1

aswstm.sys - file version: 9.0.2012.285
and no aswstm.sys.sum anymore since installing beta


I guess we all have better things to do, than testing this, installing
that, trying something else and so on.

I need my internet connection to share data, it just has to work, which
it does not since before christmas!

I was always satisfied with Avast, for many years. Ok, sometimes there
were updates which gave false positives, but that was mostly repaired
a +few hours later+, so no need to complain.

But this time I am waiting nearly a month for a working update, which
is much too much trouble!

Please: I want a solution and it would be nice, if it came finally!
I really wish I could have the old program back, really!

Cheers,

Monica

P.S. sorry for my English, but in the German forum groups
I found no similar thread.

Hi Parabell,

Glad to see I'm not the only one experience problems :D I am having the same issues as you have described which points to the web shield. Avast has been notified of this thread so hopefully we can get this fixed soon.  I can see people from Avast are on the forums at the moment so hopefully it wont be long before we get an official notice back from Avast.


Title: Re: Upload Issues (Web Shield)
Post by: Parabell on January 17, 2014, 06:17:07 PM
Thanks, Oli for inviting me to this thread!

Yeah, I am really going nut about this problem...
today I found out that many of my uploads to other of my clients had
not succeeded also - like the Dropbox-problems.

I roused their supports, too, who couldn´t find anything.
Quite ashaming to find out that it seems to be Avast in this cases,
too!

Thanks god I managed today after some disabling-webshield-frozen
Avast,rebooting Computer-tries to deactivate the web shield. So I
can redo the uploads of the last week(s).

Besides that I am not quite happy to "surf the net without condome". :->

Ok, lets wait a little more and hope for the best..

Hi drake127,

Many Thanks, Would you like a support package/log? I would be happy to email the logs over to you.

I have the same problem for days now and with many programs that exchange information with the web.

You should be able to reproduce the web shield bug because I can and it has this behaviour every time.

Windows 8 x64 machine
dropbox latest version: 2.6.2
avast version: 2014.9.0.2011
definitions: 140117-0

With all shields active throw some files in dropbox (in my case more than 350 files total size more than 2GB) because I just migrated my files from box for having sync issues there as well...now I'm starting to believe that it is avast that causes all this.

So.. dropbox will try to sync, it will show random/fake/enormous upload speeds, but nothing will be synced.

Then turn off web shield, restart dropbox then everything uploads smoothly with realistic upload speeds reported by dropbox and files appear on the web interface uploaded one by one.

If there is a way to get you guys a log or something go ahead and ask!

Just out of interest have you noticed this issue only on larger files? Can you Sync small files or is it just all files? I noticed when uploading to websites using HTTP4 and HTML5 that small uploads (less than 10mb) uploaded OK however anything over this amount resulted in Upload issues as described in the original post.
Title: Re: Upload Issues (Web Shield)
Post by: Parabell on January 17, 2014, 08:31:27 PM
I had the problems with lots of small files (jpgs 2-5mb) and
also with files about 500GB, as well on Dropbox as with some
http/https uploads (not all of them, some Sites work, some not).

My first problems I had with dropbox, uploading the latest
Wedding pics to my boss, which worked always for one or
two pictures after reebooting the computer. After three days
and only some files uploaded, I transferred the files via
network to my Win 7 professional 64Bit, also with Avast on
it, from which i was able to upload the files without probs.

At that time I had no clue and tried all the way down to
deinstalling dropbox, reinstalling, deleting caches and so on.

Since I found out Avast being the cause, I figured out that
after a reboot of my computer dropbox was somewhat quicker
launched and online than Avast, so always a few pics got
out, so that phenomenon made sense.

On my computer it worked few days to exclude all the dropbox
directories from Avast in the settings - but now that doesn't work
either. No idea, why.

It's kind of maddening...

Has anybody also a Win7 Home and Prof computer and can confirm
if this problem is existent on both versions or only on the home edition?

Title: Re: Upload Issues (Web Shield)
Post by: [Oli] on January 17, 2014, 08:33:27 PM
I can confirm the issue is on Windows 7 Pro and Ultimate versions. Not sure about the Home one.
Title: Re: Upload Issues (Web Shield)
Post by: Parabell on January 17, 2014, 08:36:01 PM
Ok, then it is just luck that my win7 prof had none of these issues,
while my Win7 home keeps me swearing..  :o

I haven't really noticed, the only thing I noticed is that if I left avast with shields on (before I realise that this was causing problems), was that when I exited dropbox and then re opened it, it manage to upload 4-5 files that were around 2MB each, then everything stalled even other files that were that small...
I hope this resolves soon...
Title: Re: Upload Issues (Web Shield)
Post by: [Oli] on January 17, 2014, 08:59:56 PM
Ah Ok, Was just checking as I have found smaller files with the flash uploader would upload ok. With normal HTTP and HTML5 uploads however the issue is still active even with smaller files.
Title: Re: Upload Issues (Web Shield)
Post by: drake127 on January 17, 2014, 10:18:16 PM
Guys, is it a progress bar issue or do you have actual problem with your upload? If you disable avast! and upload some file, does it take the same time as with avast! regardless of the progress bar? Just don't look at it.
Title: Re: Upload Issues (Web Shield)
Post by: Parabell on January 17, 2014, 10:45:37 PM
Funny Question.

No, the Problem is (as mentioned many times before from
different people) that uploads SEEM to work, but no data
at all is transferred.

You can try and wait DAYS, it is not possible to upload
even 60 small jpgs into dropbox with Avast webshield
active.

And it is no Dropbox problem, as other upload possibilties
are not working, too.

Title: Re: Upload Issues (Web Shield)
Post by: drake127 on January 17, 2014, 11:02:08 PM
You are right, I am experiencing the same issue. However I was able to upload whole CD to Dropbox at my standard speed (~ 5 Mbps). It was just Dropbox progress bar that acted funny - "uploaded" few MB instantly, then got stuck for minute or so and then did the same until the upload completed.

From what you are saying, you experience a little different behaviour which prevents you from finishing the upload. Am I right? Can I do anything to reproduce it? How much RAM do you have available? How fast your internet connection is?

Hi Drake, My personal experience has been that the file has claimed it has "uploaded" its self along side setting a super unrealistic upload speed. Then when the upload "finishes" the upload has only been 1% complete in comparison to the "completed" version the avast shield provides. (I included screenshots with my logs sent to your email address :) ) If i disable the shield everything goes back to normal but if I re-enable the shield the problems come back not just on sproutvideo but also on dmcloud (using a flash uploader) This bug isnt affecting YouTube or any Google services. It seems to be down to upsetting a JQ/Json Lib. This is the error i found when debugging dmcloud. 

19:36:54.451 SyntaxError: JSON.parse: unexpected end of data jquery.json.js:38 so something is interfering with the data stream. Json/JQ thinks the file is still going and then panics. the json shows the actual speed while the scripts have been modified when the web shield gets between them.

Just reading what Lukas has said to the dropbox thread. Seems like a very hard problem to re-create. If theirs any data you need do let us know! :)

Quote
"Hello Guys,
it seems this is really caused by the nature of the WebShield implementation. The super-fast upload phase is caused by the fact, the until avast buffers are filled, the data is consumed by WebShield, scanned and then passed onto the network. There the speed should be appropriate to your network speed, however since the application (dropbox) has already sent quite a lot of bytes, it would seem as stalled for a while. In total, the speed shouldn't be affected, the total time should be the same, however you could see these super-fast bursts. We haven't experienced any complete stalls or aborted uploads though. We will look into this and post you soon.


Sorry guys,
Lukas."

Just retried that with the beta. Uploading several files to DropBox and I can say the progress bar is really confusing - at my current location, the file says: 3 minutes left (with WebShield off), with WebShield on, it went straight to 75% and said 5 secs left. However, it still took 3 minutes to complete the upload and the files were uploaded correctly.

Application uploads will go through web transfers (http and HTML5 web apps) won't as they are able to compensate for bad/strange uploads. Dropbox is built on S3 and ive found no issues using the AWS S3 uploader myself. However other applications that rely on a linear latency system will act up upon uploading using HTML5 uploaders and Flash Player uploaders which often interface directly into the API backend

Uploads failing are web app based using server side scripts to confirm the upload being successful are resulting in quicker than normal termination of uploads as the Avast web shield is providing an illusion of a fast connection by gathering information of the hardware spec to use as a bandwidth throttle. 
Title: Re: Upload Issues (Web Shield)
Post by: lukor on January 18, 2014, 12:57:55 AM
We were trying hard to optimize the webshield's operations to consume the data as fast as possible that we forgot sometimes too fast is also a problem.

This is clearly a bug and now, when demystified by other fixes inside beta, it's cause is also very clear. We will come up with some solution, even though it's not an easy problem. It's somewhat complicated to persuade the client to slow down.

Thanks. Lukas

Lukor, please try some more files with dropbox.

Try to copy a whole dir with perhaps about 60 files.
5 files are the amount which I sometimes get up
by luck, but more I have never got completed. :)
As mentioned, not in days.

In some webuploads I geht the same problem,
with unrealistic speeds, the Progress Bar jumps,
but after "completing" upload (get the message
from the site) there is nothing on the server.
 
I had that on two sites with about 20 big zips.
Title: Re: Upload Issues (Web Shield)
Post by: Parabell on January 18, 2014, 10:11:34 AM
Found something out:

It is Dropbox (trying to synchronize) which causes Avast to
freeze, when I try to deactivate the Web Shield.

When Dropbox synchronization is paused, Avast is able to
deactivate the Webshield without freeze.

But SOMETIMES Avast seems to hinder Dropbox from getting
into "pause synchronization"-mode. In that cases it seems
that Dropbox is freezing (but is not, the task is still active,
only needs minutes to get in pause mode).

If Avast webshield is paused, Dropbox will behave completely
normal and responsive.

They really dont like each other anymore...  :o

Monica

Hi Lukas, Many thanks for the prompt response/update. I know this might be a silly question but through i would ask it anyway. Has the web shield team considered using a bandwith controller/throttler that an end user can setup on the AVAST client to prevent the faster scanning from happening?

Ive also noticed that an application still being sand-boxed by the web shield can crash the AVAST application even if the application being sand-boxed has been terminated.

Just a note about a workaround: you can always switch back to the proxy mode. 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.

At the moment I disabled the webshield permanently, 'cause nothing
else helped.

Is this workaround a replacement for that?

That workaround is an ini file edit. What the ini file changes is the shield's streaming updates back to the old version. Hopefully we can figure out the patch replacement but until then this is work around. I herd the beta version also has this built into the install but will need Lukor to clarify this.

Follow up:

I was working today with some files on my dropbox folder and intentionally left avast shields activated in order to see what will happen on save etc.

I noticed that when I saved a .psd file and also uploaded 2 .jpg exports (total of 3 files, all together around 8-10MB) they uploaded correctly. At first dropbox did report crazy fast / unreal upload speed also reported by other people here, but after a couple of minutes the files were uploaded correctly...

So I assume that the problem occurs when there are multiple and/or large files thrown into the dropbox folder.

In my case I used only the dropbox windows application and since drake127 asked, my machine has 16GB of RAM, i7 3770K, an SSD and a broadband with around 1mbit upload so it definitely isn't a specs issue here.

I'll also try the .ini workaround now and report back if I have anything new.

EDIT: I tried the .ini but I always get access denied on save. I even tried with all shields off and avast service stopped, still the same. I'm on Win8 Pro x64

EDIT 2: I solved the problem with editing the .ini by opening notepad as administrator FIRST and then opening the .ini file you suggested. Hope it helps someone ;)

EDIT 3: I can confirm that the workaround of the .ini file solved my upload problems for now! thanks lucor!

Also having problems with Web Shield. Noticed this time round that re-enabling the shields while uploading to dmcloud and sproutvideo causes the antivirus UI to crash and then upload problems come back as soon as its re-enabled. The Web Shield is throttling/using up the bandwith which has been reserved for uploading files which is causing issues.
Title: Re: Upload Issues (Web Shield)
Post by: lukor on January 18, 2014, 09:19:48 PM
Guys, about the UseStreamFilter=0 workaround:

1. What you currently get in your avast installations are two separate implementations of WebShield. One, older, but verified, uses proxy on localhost. Second, newer one, which we call Streamfilter uses WFP windows api to filter the connections without the need for proxy server. You can switch between these two by the ini file.

2. Proxy mode is used on windows Xp and Vista, where the wfp api was not present or was not mature enough. On Windows7 and later you get Streamfilter by default.

3. We consider Streamfilter to be better, faster and we generally plan to improve Webshield mainly in the Streamfilter implementation. Being a new code it seems it still needs quite some polishing. The same was true with proxy Webshield, years ago. Sorry for that.

4. Switching to proxy mode should provide you very much the same protection as Streamfilter does. It has its own issues but if you are happy with it you can stay in proxy mode as long as you wish.

5. It is possible we'll add the switch into the troubleshooting section in gui, since basically that's what it is - a troubleshooting. However the default will most probably remain as it is - no intention to turn it off globaly (as some suggested they expected that with the beta)

6. You have to edit the ini file with notepad (as administrator) or disable avast self-defense to be able to.

Thanks for the response Lukor. I understand that sometimes features get pushed out without the right net environment testing, Hopefully we can figure out a way of bridging the gap between the client and cloud version of the client. The troubleshooting method pushes a simple fix however as the shield becomes more complex the requirement of having the system in the cloud will mean updates being done on the fly. The idea for the upload/download cloud manager system came to my mind when looking at digital distribution platforms (it's not the same thing but data does get streamed down the line) The ability to tinker and switch would be a wise move as becoming beta testers for a product that isn't ready isn't good for quality. After using Avast for many years without issues version 9 has been painful when it comes to performance. If it's the buggy web rep plugin that's blocking websites when they are unchecked to be blocked or the new and improved web shield. Avast 9 hasn't been a good step in quality. I really appreciate the support and community help. We want to get this bug fixed as much as you do! At the moment I have been unable to upload video content to my websites for around 4 days without compromising my shields, The traffic rank has decreased and overall things aren't looking good. I have to make a choice soon if i want to be a product tester or use a more stable/reliable product. Hopefully we can get this resolved.

Many Thanks
Oliver

Ok the INI file doesn't have a general section. Do you want me to add the pasted information above?

I've followed this thread for any updates in relation to the web shield.

Thanks
Oliver

Ive had an idea for testing the shields at a test/development site. You could attempt to use the VLab's HPC rig and then attach a router/firewall/switch that can do bandwidth capping/traffic shaping to emulate the bug. It's just an idea but thought it would be worth sharing.

Hello again,

I am trying this webshield.ini thing right now.
Tthe tips von wefixit with the notepad in administrator-mode helped
a lot! :)

It seems to work, but first after reboot it looked like dropbox was again
not syncing, stuck some minutes again with the same (small) file, giving
different upload ratio all the time, but after a few minutes it started to
upload for real.

That´s better.. :)

Thanks!

I've tried the proxy fix this morning. It worked well until rebooting the machine. The problem came back and I've been unable to upload due to Web Shield.  :-( Lukas mentioned that proxy mode has some pros and cons. What are the cons of proxy mode? Feeling a bit sad about the situation.

I am really surprised that switching to proxy would help only after reboot? Have you restarted the service before rebooting? Can you verify, that you are indeed "in the proxy" mode after reboot?


You can do that for example by:
1) checking that aswstm.sys is not running
- Run CMD as administrator
- type SC QUERY ASWSTM
- if it says RUNNING - you are running streamfilter, if not, you are either switched off or running a proxy mode WebShield


2) check that proxy server is listening on 12080
- run CMD as aministrator
- type netstat -a -p TCP |findstr LISTENING
- do you see a line saying 127.0.0.1:12080 ?
- if yes, we are probably running there in proxy mode


Since proxy mode is in avast for years and we have never heard about upload problems before, I really have some troubles believing this would be a new bug in both StreamFilter and Proxy based WebShield implementation, especially knowing the fact, that there were no significant changes is Proxy-based webshield for some time.


Lukas.

Ok, after one day with heavy uploading and another reboot it still works. :)

Thanks a lot!

I still worry about people who still think their dropbox is damaged or
the sites they´re uploading to. In the dropbox-support forum there
were some people who thought about Avast least and only checked
that when some of us told them to test it out.

This problem does not always look like an anti virus issue, at least
to those who are not programmers or other system-near workers.
I am really no noob, but didn´t get all which was told in this thread. :)

Perhaps it would be best to give this out as an Avast message, as a
popup, like the one from today about the telekom-hijacking attack,
though I know lots of people (with computer experience near zero)
who just click that messages away. :-(

It were people like that whom I recommended Avast so dearly,
because it was so good for them to get spoken messages like
"Achtung, Sie haben einen Virus auf Ihrem Computer"! :->

P.S. Hm, what will the patch do? Override the stream filter at all till
the problem is fixed or give the choice to those who have problems?
And will it come automaticly?

Hi Parabell the new installation of Avast build 2013 will help fix the web shield. :)

I would recommend removing the previous edit to your INI file (stopping the shield and the in-built defense then removing the line about streaming web shield) then update to version 2013)

Hello everyone,

this thread is quite old but the last days I have come across the same problem with build 2016. Everything behaves just like the other users describe, I was able to fix it with the ini file workaround. I wonder if the bug was considered fixed, as it obviously isn't.

With best regards

Edit: Sorry, didn't see that there was another thread on this topic.

The latest avast version is 9.0.2018, so the first thing you should do is get the latest version and see if that has resolved that issue.
