Kaspersky Internet Security
Full user review
"Maybe- maybe not"
We dont know. let's check the independent lab test later.
Kaspersky 2012 was blocking valid installed softwares to connecting internet with some of its proactive solution, this new version maybe still do that. The 2013 turtle interface are still questionable. Not much happends with this new 2013 version, more than it make the system slow exact as before.
If you want a protection that won't slow down your system, highest possible security, cost-effectiv included, and with a beatiful streamlined interface go for G-Data, AVG or AVAST.
