First, I found very strong slowdowns in web browsing. I mean, when the virus is launched, namely its normal use, and an ultra-powerful PC, loading each web page automatically calls between 5 and 30 seconds. Yes, you are faced with a blank page waiting for the slightest display during that time.
Although I have sought a solution in the editor forums: nothing. The problem is reported since the release of the software, but no solution is proposed. Should remove items one by one to clear the fault? Nothing at all: I'm removing all the fault persists.
Admittedly, it is difficult to judge a product on a rare fault, although others complain of it in the official forums, in vain. That is the assessment of the technical support of the editor is relevant.
I got a referral to a Korean page. Then in English. In short, I wrote my support request in broken English, but clear. After one week, the response: Contact the French media. A little too languages intertwine in inefficient technical support interface.
More generally, Kaspersky tends to a laughable market segmentation. At one time, the included antivirus everything. Now, this is only entry level product that is supposed to protect only against viruses. However, it becomes embedded in the browser and monitors network traffic. But that does not mean it will protect you effectively against web threats. For this, you will go upmarket. Either. Although, suddenly, I wonder what is this: difficult to use an offline computer from the Internet at the time of the "cloud".
But the biggest problem probably lies in the qualification "virus". As for me, this is any software that installs without my knowledge and whose activity is parasite in any way whatsoever. Enter my definition countless "adware" who install, without the knowledge of the user, additional bars in browsers, or change the home page of it, especially when these are specially designed for it can not be uninstalled. Kaspersky ignores these threats, or at least the threats that I met why other software came to my aid.
In short, a disappointing software, inadequate, alone, and even productive. It is time to consider other competing security software.
