Fix for WebShield download issues

Any new updates? Still having to disable web shield whenever I download a file, doesn’t matter the size - ie: just installed an Adobe Flash Player update that was a mere 1 mb. It would not download unless Web Shield was disabled.

I am also still unable to view YouTube videos unless Web Shield’s disabled (freezes within the first few seconds).

Everything works perfectly when Web Shield is disabled.

I’ve been patient, but I’m starting to think these issues are borderline irresponsible. It’s approaching a month now and these issues are an inconvenience on a daily basis, multiple times a day. I’ve been using Avast since 2009, and have never encountered a problem as browser-breaking as this one until this 2014 edition.

Are you sure you are running Avast! 2014 9.0.2013?

Yes, I have checked for the respective files, and have the latest versions.

Which files? Can you post a screenshot of the version info of aswstm.sys?

I am using Avast version 2014.9.0.2013
aswstm.sys is version 9.0.2013.292

:cry:
Hmm, so you are indeed running the latest version. So, no, there hasn’t been any updates since yesterday when 2013 was released. We were so far under the impression that the problems were fixed. What is your OS version?

Could you, please, switch to the proxy?

Webshield.ini

add the following two lines;
[General]
UseStreamFilter=0

  • restart after the edit, or at least restart the “avast! antivirus” service
  • edit the ini files with notepad running as administrator

Strange, I’ve been testing some YouTube videos, and now and sometime they play, and sometimes they freeze, which is an improvement. Crossing my fingers the problem will resolve itself over the next few days.

I also test downloaded another file - a larger one, 69.3 mb from the Blender site (http://www.blender.org/).
Downloading with Web Shield on - it downloads, but Windows says the file is corrupt.
Downloading with Web Shield off - no problems.

If I switch to the proxy, will I need to manually turn it off for future Avast version updates?

Thanks for your support.

Edit: My OS is Windows 7 Professional.

Lucern,
this is something definitely new, not a known bug to us.

Could you harvest some logs for us?
To do that, please create StreamFilter.ini in the avast! program data folder with the following content:

[Common]
FileLogLevel=0
RecordInput=1
RecordOutput=1

-restart the shield afterwards
-you might need to edit the file with notepad running under administrator, otherwise self-defense will prevent you from editing it.
-after the problem appears, could you
-stop the shield
-send us the C:\Programdata\Avast Software\Avast\Log folder
-send us the C:\Programdata\Avast Software\Avast\nsf folder

Thanks. Lukas.

I remember reading in earlier pages of this thread other users describing the same bug - downloads would hang at 99%. If they finish (sometimes they will simply time out), they are corrupt. I’ve been experiencing the same issue since the beginning of the installation of the 2014 version of Avast in December.

I did as you said, added the lines to the StreamFilter.ini file and recreated the problem - but the Log and nsf folders were not created, so no logs were created. Is there another step I need to do?

Edit: I also restarted the Web Shield after making the edits to the StreamFilter.ini file before recreating the problem, and stopped it afterward.

If you could not find the log folder, you are probably looking into a wrong place. The log folder is always there.

C:\Programdata\Avast Software\Avast\Log

C:\Programdata\Avast Software\Avast\Nsf

Of course, you must be running streamfilter, you can verify that by checking if aswstm driver is running, such as:

SC QUERY aswstm

You should also stop the webshield after you have re-created the problem - so that the logs gets written to the disk, but the files (with zero length though) should be visible on the disk as soon as the shield starts.

I’ve attached a screenshot of my Avast folder - is this not the correct directory?

Yes, incorrect one.

Please you the one I’ve mentioned before.

Go to your Windows partition and write “programdata” manually, as:

Thanks for the tip, Lord Ami. It was a hidden folder, and selecting the option to show all folders displayed it.

I’ve attached the StreamFiler.log file from the log folder. The forum will not let me attach files from the nsf folder. I tried to zip the entire folders but the forum will also not let me attach zip files.
Let me know if I did this right or not.

Edit: Added the StreamFilter.log file.

Lucern,
we would need the complete nsf folder contents. You can upload the zip file to your anonymous FTP server here:

ftp.avast.com/incoming

Or mail it to my email address (its rypacek {at} avast {dot} com)
Thanks.L.

You can also use this public file depot:
http://www.uschovna.cz/en/poslat-zasilku

Uploaded the nsf folder to the incoming folder via ftp.
Let me know if you received it or not.

I went thru that too. nsf and other folders are protected by avast! I believe, so in order to use the contents, you can also copy them to Desktop for example :slight_smile:
But FTP is the best choice I’d say :slight_smile:

My bad. I didn’t completely read the sentences. Yes, forum rules may restrict attachments. I read that the folder didn’t allow you to use the files ::slight_smile:

@Lord Ami

It’s a feature of the Avast forum, not with permissions on my local machine. The Avast forum only allows certain file extensions to be attached. .log is one of them, but the two file extensions in the nsf folder, .dat and .xml, are not allowed extensions to be uploaded to the Avast forum.

Hi Lucern,
sadly I am not able to locate the files on the FTP. I’ve found a folder NSF, but it was empty. We really have to make this whole process somewhat easier, it was even hard for me to locate the server’s internal name here.

Could you give it a last chance and try to upload the NSF folder zipped into one archive. I believe the security policy on the FTP prevents you from seeing anything you create - so I guess even the folder NSF is actually not visible to your FTP client and therefore it might fail to store the files there. ZIP file should solve this.

Sorry for the hassle.
Lukas.

Hi Lukas,

Just uploaded a zip file with the name “nsf-lucern.zip” via ftp.
Let me know if you’re able to locate it.

@Lord Ami
Thank you for your advice. :slight_smile:
