I like kapersky, I use it for years and I'm happy, but for the 2013 version, I struggled to make it work, no option to enter the activation code, j 'kapersky had to call customer service for a hand, and in fact, it was settled very easily like that, but hello time wasted trying to do myself. I put it down to a bug or perhaps a lack of explanation in the manual when the previous license has expired. otherwise the product itself gives me satisfaction.
