Had the last 2 years good experience with Mc monkey, but in December 2014 to extend no attractive offer. Have decided to Kaspersky. The frustration-free packaging contains a CD, but uses only Windows computers. That's why I had to download my software from the Kaspersky website. That goes smoothly. The software can be tested 30 days for free. I have not done since the Frustration-Free Packaging includes the product key. Thus, I immediately made the activation. Have 3 MAC's protected. A virus scanner is working from the storage media of the MAC / PC, the other is responsible for the web. At the beginning of the performance loss is noticeable; which gives, however after some time. Updates and Site testing (phishing) also work well. I'm very satisfied, was a good choice to try out Kaspersky. Can I recommend, especially since this variant "Multi Device - 3 units, whether Mac or Windows PC, Tablet iOS or Android, iOS or Android Smartphone is a very broad, probably currently still unique.
