I notice there is a high CPU usage by F-Secure Firewall Daemon service (fsdfwd.exe) when I enable firewall rules. When the firewall rules are disabled, the CPU usage goes back to normal. How can I fix this issue?
The root cause was because of too small DNS cache in F-Secure Firewall Daemon services and was fixed by increasing it. We have prepared a hotfix to replace the problematic firewall binaries. Proceed to contact F-Secure Support to obtain the hotfix.
