Kaspersky is one of the major names in digital security. Its suite Kaspersky Internet Security for OS X offers the best protection with the least impact on productivity, with some specific features.
Though malware for Mac devices is not so numerous and various as for Windows, other threats (like phishing or online payments fraud) are just as serious. In fact, the primary mission of security suite for OS X is protecting online activity. And Kaspersky does all that.
On finding a suspicious file, Kaspersky uploads it to its cloud to do the analytics and return with a verdict. It may detect also malware for Windows that can spread itself stealthily through Mac computers.
For online shopping the suite has a safe web browser and a virtual keyboard (to avoid key loggers logging the keys you press and thus obtaining your credentials). There are also tracker blockers, a webcam blocking module, parental control and so on.
All the features are available under general type of license, with no price levels. That makes Kaspersky a good option for Mac computers, if you’re not satisfied with basic security level and want to strengthen it.
