Kaspersky continues to grow as a household name every year, and for good reason. Over the years, they've completely rebuilt what it means to be an antivirus engine, while increasing the overall user experience.
The top testing labs around the world have given Kaspersky high awards and certifications:
West Coast Labs
Anti-Malware
OPSWAT
Virus Bulletin
AV-Comparatives
AV-Test
Kaspersky Internet Security 2012 is just as strong as ever when it comes to antivirus and firewall protection, but they still aren't as refined as some of their competitors when it comes to overall usability.
For one thing, their user interface is still full of nagging issues that should have been easily fixed, but weren't.
Protection against zero-day threats, and emerging viruses is strong according to tough, independent testing around the world. Their firewall is top-notch, and their cloud-based antivirus protection is on the move.
However, there are several holes in certain key areas that could make or break your final decision about Kaspersky Internet Security: their antiphishing scored lower than even Internet Explorer's in some tests. Their social network protection isn't as holistic as it could be. And their tech support is rife with problems.
We still like Kaspersky for its sheer protection power, but it's sliding back on our list this year due to some missteps that are too much to ignore.
