With F-Secure now I have had good experiences and the whole thing runs smoothly and does not burden the system noticeably. It is nice that you have a Zusatzapp here - Freedome - noticed. This IP is masked and you can surf almost "invisible".
Installation is simple. Delivered one gets only a cardboard box in which there is a code. The software is downloaded and activated using the code. A simple thing that is going well and hopefully lasting protection.
