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.

Best regards,

Dear Vad

Thanks for your prompt reply

Few clarification questions:

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

yes,client updated the version from 12 to 12.31 and he got the issue.Version 12 no issue

i just updated from 12.31 to 12.32 and i got the issue,previously it was working fine

2. What OS is/are affected? windows 8.1 and windows 10

Network connection malfunction is shown in 2 cases:

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

the service is not running

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

Kernel Driver - running

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

Thanks

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

Vad

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

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?
