Kaspersky Internet Securitiy 2012 sets new standards. The surface has been simplified and even more clear. This is the most "normal" users who want to just have a functioning and easy to use anti-virus software like. However, advanced users are still all possibilities such. As the firewall or the network monitor on a continuing, nested menu open. The menu system is easy to understand and is not even very deeply nested.
I have tested Kaspersky 2012 on a PC and three laptops. The PC and laptops are normally fitted and no high-end machines. On all four devices no or only very slight loss of speed when you start Windows and during the operation were observed.
Kaspersky 2012 is great software that I can recommend to anyone who wants to protect his PC.
