Kaspersky Internet Security 2010 earns high scores for strong malware detection, efficient performance, and a well-designed interface. Updated, 9 April 2010.

Overall, Kaspersky Internet Security 2010's interface is easy to use. The screens are informative without being overwhelming. The main window is clear and easy to navigate: It includes a left pane for navigation, and a right pane containing the various options. Rather than break out firewall and antispam, for example, these features are organized by general topics, such as My Protection, My Security Zone, Scan My Computer, and My Update Center.

In detecting active malware infections on a PC, Kaspersky Internet Security 2010 performed well. It found all malware samples and disabled 87 percent, but removed all files for only 47 percent of the test infections (that score for removal is about average; no suite managed to remove all traces of every infection). And Kaspersky tied McAfee as the top performer in rootkit detection, finding and removing all inactive and active rootkits.

Kaspersky Internet Security 2010 was above average in detection and disinfection of malware through behavioural scanning (detecting malware based solely on how it behaves on a PC). It detected 87 percent of malware samples through behavioural testing, disabling 73 percent, and fully removing 60 percent. This test is a good indicator of how well an antivirus application can handle brand new malware threats for which no virus signature file exists.

In old-fashioned signature-based detection of malware, Kaspersky Internet Security 2010 scored a 97.4 percent detection rate - an impressive result, but a bit below the top score in this test, a 99.9 percent detection rate.

Kaspersky Internet Security 2010's impact on system performance is minimal. A PC with Kaspersky's suite installed booted in 43.4 seconds on average, beating the average starting time by 3.5 seconds. The same PC running the McAfee or Norton suites, by comparison, took about 50 seconds to start up. Kaspersky didn't significantly affect performance during normal desktop use either. Scan speeds were okay, but not outstanding. It took 4 minutes, 48 seconds to scan 4.5GB in our on-access scans that determine how long a suite takes to scan files when you open or save them.

Kaspersky Internet Security 2010 is the latest version of the popular Windows anti-malware package, complete with a new 'sandbox' mode.

Just as Christmas seems to come earlier every year so does the season for releasing next year's crop of AV products. So it is with Kaspersky Internet Security 2010, the latest iteration of the respected security bundle.

Kaspersky Internet Security 2010 contains all the usual protections found in its rivals with the exception of data backup provision. So you'll find antivirus protection for files, email, web browsing, applications and processes.

You also get a bi-directional firewall, anti-DOS protection, anti-spam as well as anti-phishing and banner ad blocking. So, no surprises - a pretty comprehensive set of security tools.

So what's the new version of Kaspersky Internet Security 2010 got over its predecessor? Changes are fairly subtle but worthwhile.

The already quite well developed user interface has been given a lick of paint (still green paint though) and remains easy to use for such a complex product. Other changes include antivirus protection for instant messaging (IM) sessions and a URL Advisor to combat phishing and dodgy websites, plus a 'quiet' gaming profile.

Internet security news and reviews

The major new feature in Kaspersky Internet Security 2010 is Safe Run, which lets you run suspect apps or links in a virtualised 'sandbox', thus isolating it from the OS. It automatically added Internet Explorer to the sandbox, a fairly logical choice.

To run the ‘sandboxed' IE in Kaspersky Internet Security 2010 you have to click on its icon in KIS2010 and the virtualised version is denoted by a ghostly green outline to its window. While this is an interesting development, offering good protection against zero-day threats, it did whack CPU utilisation for a six, making our none-too-fast PC even slower. We also experienced a number of lock-ups of the PC using this software.

Kaspersky Internet Security 2010's anti-spam provision is a bit better too. Spam by default prompts you to deal with messages as they arrive rather than silently and automatically deal with them, as you might find in rival IS packages. As we had over 4,900 emails in our honey-trap email account, this could be rather tedious. However, when we clicked Close, it then went on to automatically process our spam mountain.

It was slow but pretty accurate, mis-indentifying a low 1.5 percent of our spams as genuine emails, not bad when it hadn't been ‘trained'.

Features-wise Kaspersky 2010 is a definite step-up from its predecessor. It’s always had a strong feature list but it trod lightly on our clunkier system, having little impact on performance - providing you discount the high CPU use in the Safe Run ‘sandbox’ mode. Kaspersky Internet Security 2010's detection rates have been higher in the past but it remains a top five security bundle.
