Kaspersky for years is always in the first places, when it comes to Internet security. In all test Kaspersky is ahead. I had always ESET and was really pleased. But ESET ran out and Kaspersky was in special and I thought to myself, "if the program is the best then I should afford me". Well Kaspersky like in the detection of viruses and Trojans indeed be number one, but probably also in the ranking disgruntled customers. Annoying is already the Automatic Updates usually does not automatically download. No, it displays a message that the computer is in danger and you have to download the updates yourself. While this is annoying, but no problem. I installed Kaspersky for both me and my sister. When I am my sister's PC the clock Ground surrounded on summer time (yes, that was stupid and unnecessary to make the manual), the program disabled. Annoying but I thought no problem. Then I pull the program just new to that CD I'm still. Well, the CD could be die not start even though they had been inserted only once around. I actually had a new program Kaspersky Internet Security 2014 and the sale could be then install. That my sister program had nearly five months duration. On my PC, I had the beginning of March, Kaspersky Internet Security 2014 installed and to the (not) automatically updates no problems. But yesterday, the program has deactivated without any reason. Simply the antivirus program is disabled. It was because I had to install the entire program. Now when I tried to do that today, the program was suddenly intact. I do not know how long it holds and when it rumspinnt again. From the reviews here I see that I'm not the only one having problems with the program. Everything pretty annoying. Kaspersky Internet Security 2014 has been installed so recently. But that was the last time I bought Kaspersky. No matter how good it should be. In the use and handling, it is flawed.
