Following their recommendations i have disabled the DNS-cache in order to prevent DNS-cache poisoning.
A few days ago when i was checking some settings in "Services" i noticed that the DNS-cache was enabled !?
I tried to disable it, which was denied because: "other services depends on it".
I found out that it was a process from CyberGhost VPN which i installed two months ago that needed the DNS-cache running.
But, during the installation there was no information regarding activation of the DNS-cache !?
That is unresponsible, not telling the user they are messing with the security-settings.
So be aware, if you like me have disabled the DNS-cache in order to prevent DNS cache poisoning, then watch out if you install CyberGhost VPN or similar VPN-clients !
I posted information about how to activate and disable the DNS-cache with a bat-file here:
