No system slowdown

Besides a good antivirus, an anti-virus program, the system should not unnecessarily burden or even slow down.
F-Secure runs with me now, just six months and I can not notice any pace losses in the system. The program runs silently in the background and logs only when needed, that is most of the time not you noticed that an anti-virus program is running. That's how it should be.
Additionally, I have now installed "Freedome" on my PC and here I note no performance degradation.
Surfing seems to be not a bit slower. For a VPN tool to perform well.
Installing Freedome is simple. Download the software, the exe and click within one minute runs Freedome.
Unfortunately, the surface is only available in English and can not switch to German. But it is very tidy and easy to use.
The data that is passed over the Freedome server are encrypted. F-Secure promises beyond that to save any data transmissions. Whether that's true? After all, is not an American F-Secure, but a Finnish company.
