I have Kaspersky since 2013 he and am very happy version. Until now had no viruses or other! I have it changed to the 2015 version. I must say personally I like the surface of the 2014 it better. But that's always a matter of taste! I am my Windows 7 Gadget Kaspersky used what he was abolished in the 2015 version. Pity! Therefore, I have re-installed Kaspersky Internet Security 2014!
