I use Kasperki for more than 5 years and had previously among other things, version 2013. This version was flawless. Since I have the version 2014 installed I only have problems. Significantly poorer performance, frequent crashes, only problems. This is the version of the mangelhafteste Kasperski has delivered. In my eyes it is an impertinence which is sold such a product! I would nihct longer buy the product.
