I use Norton already for 4 years and have never had any problems with fours. When you order the CD on Amazon, it is much cheaper, like when you order directly from the website of Norton. When the program is installed, clicking only to prolong and enters the new product key. The remaining days will then be posted automatically good. I think it's important, if you have a security program to which you can rely. I can only recommend Norton and because the inexpensive products are perfectly adequate.
