Effective protection for the whole family

I've had very good experiences with both virus scanners. Kaspersky is particularly recommended because of the price / performance.

Good to know: the 365 Day runs from the time you enter the first license for every 5 licenses. You need the time being only 3 licenses and 2 only in half a year, you're probably better off with the license pack for 3 PC because the remaining 2 licenses would then only be valid for six months.
