My current license is still valid more than one year (until September 2014), but the advantage at Kaspersky is that you buy a license, not software. The only thing that interests me in this software is the paper that is in the box that contains the activation code. What I mean is that I can buy Kaspersky Internet Security 2012 and then in 2014, 2012 use this license on the software KIS 2014. And my new license will be well valid for 2 years from the date I will activate the license. I had done this in 2012 by purchasing a license in 2010 for 2 years. And to my parents, I bought them in autumn 2012, a KIS 2011 (plus it was an English import, I was a bit scared, but it will, I could turn it on KIS French version ).
To use the license Kaspersky internet security 2012, 2013 or 2014:
=> Please do not install the supplied CD as it is an older version.
=> If Kaspersky Internet Security is installed on your PC, go to the License Manager and click "activate new license". You simply specify the license number provided in the box logiciel.Une the license which is in a box KIS KIS 2012 march on on KIS 2013 or 2014 (I always bought licenses dating for less than 2 years expensive, and I always use the latest version of KIS, it always worked), there even has big chances that it work with KIS 2015 (when it ships), but personally I have tested with 2 years apart.
If Kaspersky is not installed or if you want to install the latest version (eg 2013 or 2014):
=> Go to the official site of Kaspersky. Click on the "download" and click on "Products to download" (do not click the "trial" because you have a license, you need the complete software).
=> Click "Kaspersky Internet Security" to arrive on the page with the latest version to download. Click download to get the latest version (2013 or 2014 from the date you go).
=> Install Kaspersky you just downloaded (if you had another antivirus before, careful to uninstall it before)
=> During installation, there is a time when you will be asked if you have a license number. Indicate the No. of license comes with Kaspersky Internet Security 2012 (shown in a paper in the box of the software). Well, if you miss this step, you only go after installing the license manager to activate the new license.
Warnings:
=> If you have an active license, although the last 5 days to wait before activating the new license, otherwise you will lose days (licenses are not combinable, except for the last 5 days).
=> If you buy a license from 2 years to 3 PCs: as soon as one active license on 1 PC, it is activated for 3 PCs at once. A license for 3 PCs, not 3 licenses for 3 PCs. If, for example, the active license is 2 years on the PC # 1 September 10, 2013, will be valid until September 10, 2015 on 3 PCs. Even if you install Kaspersky on PC # 2 several months later with this license, it will only be valid until 10 September 2015. Ditto for the PC3. In short, it is the date of activation on the PC 1 determines the validity of the license on the PC 3, quelquesoit the installation date on the other 2 PC.
For the software itself:
For several years I use this suite of security and it works really well.
For 2 years, I also moved my parents know nothing therein computer. The operation and automatic settings work very well, it avoids they call me every 3 days, saying "security software asks if I have to accept it, what should do" (well, it happens sometimes, but it's rare). Above all, I do not have to intervene with them to remove spyware or other crap (which has happened several times before when they used Avast).
For more advanced users, you have access to a lot of settings (I will not detail them here, there are far too ^^ and google is your friend).
Security suite that makes antivirus files, mail, internet and chat - Application Control - System monitoring - Firewall - Proactive Defense (defense against new threats which are not yet included in the database) - Intrusion Prevention (in case attack, KIS blocks any activity from the attacking PC) - Anti banner - Self defense - Game Mode - Parental Control - Network monitoring - etc ...
In terms of analysis, in addition to conventional analysis, we can do a search for vulnerabilities that will alert us to some of our settings and whether some of our software require security updates (flash, java, windows update , Adobe reader, Quick Time, VLC, etc ..).
You have access to a protected environment. When launching an application in this environment, we are in a completely isolated virtual environment of our operating system. There is also secure browsing, but I feel that this is the same thing, and having put aside this option lets just make a shortcut on the desktop to directly launch our browser in safe (it saves a mouse click ^^).
For antispam, we must think of the train otherwise not. And even after training is not the top, I would say that this is the weak point of Kaspersky, and it is also because of antispam his notes down in the comparative. Fortunately, this is not what I look when I buy a security suite, anti spam my internal messaging being sufficiently effective.
We also have some tools, such as removing activity traces (cookies, caches, logs, etc ...), System Restore, help with the configuration of Internet Explorer, the option to create a CD or USB drive recovery (Kaspersky Rescue Disk).
And for those who use Internet Explorer, you will have 3 browser extensions: anti banner, link analyzer, and a virtual keyboard which is super convenient. These extensions are supposed to walk on Firefox, but in practice that there is a dice update Firefox extensions are not compatible (Belizean above, kaspersky should make an effort, it's a bit abused).
Fortunately, extension or not, it does not prevent Kaspersky to protect us in our navigation. Just last week, he blocked a script on a site script that probably came from a pub (kaspersky makes its analysis before allowing the page and the ads appear, so even if it was more adblock blocking pubs, kaspersky notify us if at the base, there was a pub with a malicious script).
Well I forget a lot of stuff, but I've already write a novel. ^^
