The F-Secure Internet Security 2015 Upgrade - 1 year / 3 PCs is ideal if you are satisfied with the product and the following year using the product also. However, a little more price difference should be between upgrade and full version. You do not even save 3 euros compared to the full version! So I take that upgrade from 3 star. 30% difference should be between a full version and an upgrade at least. The course does not change the fact that F-Secure Internet Security is an excellent security solution that runs perfectly well on older computers and the PC does not slow.
