We are using F-secure Client Security 12.31 in our clients. In some of the machines there is a cross mark on F-secure logo and showing network connection malfuction. Further in the machine F-secure AntiVirus Firewall Daemon service is in stop state and could not be started. All components of F-secure are properly installed  and the machine has taken latest update of antivirus as well as of windows. 

 

When we uninstalled 12.31 and installed 12.00  machine working properly. please suggest.

    Hello ravi12,

     

    Few questions:

    I guess, restart doesn't help?

    What OS are affected by this issue?

    Did you install the Firewall public hotfix for Chrome crashes on affected machines?

     

    Best regards,

    Vad

    Then, most likely, you are missing specific security update. Please, check:

    I installed also the Hotfix, the same problem with this issue. What should I do now?

    Please, contact support. We will need the Support tool diagnostic information collected from one of affected machines for investigation.

    Dear Vad,

     

    i just installed client secuirty 12.32 and i get  network connections: malfunction error.some of my clients also affected by this issue.

     

    Note:Windows is up to date 

                This happens when the client is updated(ex: from 12.20 to 12.31 or 12.31 to 12.32)

     

    thanks

    Hello asanka,

     

    Few clarification questions:

    1. Do i understand correctly, that you have this issue with both CS 12.31 and CS 12.32?

    2. What OS is/are affected?

     

    Network connection malfunction is shown in 2 cases:

    1. F-Secure Anti-Virus Firewall Daemon is stopped (could be detected from Windows services window)

    2. F-Secure Firewall driver is stopped. Can be checked by running "sc query fsfw" from cmd with admin rights.

    Please, check, what is the reason in your case.

     

    Best regards,

    Vad

    And restart of the machine doesn't help, i guess?

    The most common scenario, in which driver is running and daemon is not, is the situation where for some reason version of driver fsfwd.sys (can be found in c:\Windows\System32\drivers\) and version of daemon fsdfwd.exe (can be found in c:\Program Files (x86)\F-Secure\FWES\program\) are different.

    If restart does't help, and versions are identical, please, contact support. We will need to collect FW debug logs for investigation.
