Well, I think: It is responsive, without delay call and otherwise easy to adjust to their needs. However, there are many options that are difficult to find in part because of the menu structure. It works well in the background, I had no problems. But you should uninstall its previous safety program completely, possibly for a special program of the manufacturer. Less well I like that it has been touted in many "independent" tests with the supposedly high system resources and in the end, if you set the security to the maximum value, but then slows down, after which it is pointed. Otherwise it runs far super, no problems at all, but please do immediately after installing all updates of the program, also make sure to reinstall Windows all Windows Updates! Disturbing shortcoming is the lack of support for Windows 8.1. It runs and protects, but especially downloads from the Windows App Center are possible only after turning off the firewall Kasperski. Perhaps this can be professionally configure somehow. For the average user is likely to be difficult but.
