With a few sentences: I am not a professional but now not quite inexperienced. I use Norton Internet Security for several years and this version, all I can say, is very good. The user interface compared to my previous version is more modern, more clearly and visually beautiful. The installation was surprisingly easy for me and the intelligent Work manner, during my work on the computer, all applications hedges during ongoing work. The "upgrade" version has been cheaper than buying the full version but I am so completely satisfied. So in my opinion a very good price-performance ratio. Negative arguments can I recognize and no arguments.
