  • Protection 365

    I made the mistake of using Norton and paid the price as a Trojan got in and I had to buy a new laptop. Now with Kaspersky you can see the level of protection at work and I feel 100% confident that I have the up to date protection I need.

  • works great, simple upgrades, complete protection

    I've been using this product for at least 7 years and it has never failed me. I'm still careful with my internet and online activity but who knows when something malicious may sneak in or piggy back with an email. KAV and KIS both give me the peace of mind that my computers are protected. Simplicity of upgrades is also a great feature. If you happen to install a trial version of KAV and purchase a full version of KIV (which is 1 tier of protection higher), the program automatically updates itself without needing manual re-installation of the program. You can always continually stay protected by purchasing products ahead of time and plugging in the license under new activation code. This way, when your current product expires, the new license will automatically kick in without the need for intervention. An unused license also generally does not expire. At one point, I purchased 3 retail boxes good for 3 licenses each (or a total of 9 computers/devices). I only need to protect 6 devices so I was left with an unused box. The following year, I used the license and it worked ! Program and application updates are also available during the time of an active license. This means that if you are currently using app version 16.1.x.x and version 16.2 or even version 17.0 becomes available, then you qualify for the upgrade. There are many variations of the program that should also prove to economical for most users. For example, if you need to protect only 5 computers, you do not need to purchase 2 retail boxes with 3 licenses each. There are 5 computer versions. You are also no longer limited to a single platform since there are versions for multiple device combinations (pc, android, ios). Finally, instead of the usual 1 year license, there are now 1.5 (18 month) retail versions

  • My protector for the last three years

    Never had an issue of virus attack to my system so far. Worth the saying Internet Security as it definitely the best application I can personally guarantee for. Infact to all in my family circle and friends I recommended and changed to KIS users today. Good product with reasonable resources it takes. But there was an issue of very slow updates on daily basis, which I could feel is sorted out in 2016 variant. Great !
