after years of use Avast free I switched to the paid Avast Internet Security. After detecting a rootkit, the Avast push either in quarantine, nor could delete, I had installed the 30-day trial version of Kaspersky. It was not love at first sight, everything was a bit opaque to me as a layman. So I had decided on the Norton Internet Security, because of good support and many satisfied users in the circle. Unfortunately liked my PC (Win7 64 bit) the program when FullScan not, it occurred repeatedly for errors. Here, I could not even help the prompt and friendly support from Norton. After countless times of de- and I had to install the program back. Now I am forced moderation Kaspersky users, Prgramm takes forever when uploading, because you can still comfortably drink a coffee, besides, I have despite correct adjustment difficulties while updating. Although Kaspersky announces your system is protected, the virus database is still the previous day. That makes me totally unsafe, my program is reinstalled, what am I doing wrong ??
