    Kaspersky Endpoint Security causes Yandex Browser to not work properly. Sometimes when you try to go to certain websites, they won't load. This only happens when Web Threat Protection or Web Control are activated.

    Kaspersky Endpoint Security 11.7.0.384

    Windows 10 Home build 19043.1052

    System Settings

    Operating system: Win 10, x64

    System: Intel i7-4770K

    Product: KES

    Product Version: 11.7.0.384

    Language: en-US

  • Hello! can you please give more info? Can you tell several web sites which was blocked? It will help developers to search problem in traces
  • W

    During tracing, I tried to go to bing.com which was blocked.

    @wfeldmann hello! 

    Can you please reproduce it  twice with one web site collecting:

    with KES OFF:

    1 video (that site is opened without KES protection) 

    with KES ON:

    1 traces

    2 video

    3 network traffic dump 

     - = how to collect traffic dump = -

    If reproduction of the issue requires the web browser to open web pages(such as web control non-working as expected, web page not loading, and so on), the tests should be performed in Incognito mode(also known as private browsing).

    KES11 Instructions

    1 Disable KES11 self defence

    2 Navigate to the following registry key:

    x86: HKLM\SOFTWARE\KasperskyLab\protected\KES\environment\

    x64: HKLM\SOFTWARE\Wow6432Node\KasperskyLab\protected\KES\environment\

    3 Create a string type value named DumpNetworkTraffic :

    DumpNetworkTraffic = (REG_SZ)"1"

    4 Restart the product or reboot the host

    5 Traffic dump files will be saved to %ProgramData%\Kaspersky Lab\KES\Data\traffic

    6 Once the issue is reproduced compress the whole traffic directory

     

    Do not forget to disable traffic dump collection. To do so delete DumpNetworkTraffic value.

    What do you mean by "video?" Video of what? Do you want a video of what is seen on my computer screen? A new version of KES is out, so this issue might not matter at all. I will let you know if the new version has the same problem.

    I just installed the new KES, and I still have the same problem. I will try to follow the procedure you gave me.

    Update: I tried the procedure, but could not get the traffic dump to work. x64 and x86 refers to the processor type, right? I have a x64 processor, so I created a string (right click, new, string value) named DumpNetworkTraffic in HKLM\SOFTWARE\Wow6432Node\KasperskyLab\protected\KES\environment\. The "value data" for the string should be

    DumpNetworkTraffic = (REG_SZ)"1"

    right?

    hello! it seems right, 64 s for OS, I'll try to get info from colleagues.

    not get the traffic dump

    Please try alternative way 

    If it won't work too, you may contact our b2b support service and ask for help, but, please, mention that you are from beta forum.

    This method didn't work either. I should point out that there is no traffic folder at ProgramData\Kaspersky Lab\KES\Data\, Is the folder supposed to be created when the dump is started?

    Is this what you mean by b2b support service: https://community.kaspersky.com/kaspersky-corporate-products-27

    Hello! seems to be true, than folder should appear when dump gathering starts.

    I mean - our usual support service, to whom you can call by phone, not posts on community forum. 

    Just call them and tell "Hi, I'm from BETA forum with BETA KES (or they will start asking for you licence, company and so on), Please help me collect traffic dump, I've trieed these two ways....."  and please write down and tell me in private messages number of issue (if they will create it)

    The support service helped me get the traffic dump to work. The problem was the string value should be 1 and not DumpNetworkTraffic = (REG_SZ)"1". See the links below for the videos, dump, and traces.
