The updates to Kaspersky Lab's 2011 security suites introduce a new tool for cleaning already-infected computers, as well as a system watcher, location filter, and expansion of the program's sandboxing feature. Available Monday exclusively in North America from CNET, Kaspersky Internet Security 2011 and Kaspersky Anti-Virus 2011 make a good case to longtime Kaspersky users to stick with the company while giving new users enough to consider switching.

The new version of Kaspersky Internet Security 2011 includes a proprietary support tool that the company says will install on infected computers and then clean them well enough to then continue with the regular program installation. The suite also expands the SafeRun sandbox feature offered last year outside of the browser with SafeDesktop. As the name implies, it now protects the desktop as well so that you can install programs without running the risk of accidentally damaging your system or installing malware. There's new antiphishing measures in place, and in some cases, Kaspersky said, certain unapproved malicious actions can be undone thanks to changes made to the program's proactive defense system.

Other changes include a new Windows desktop gadget that pushes system security information to an easily viewed location and is customizable so users see only the data that's most important to them. New family-based protections include control over file downloads and video game usage, and a new location-based filter can be used to block incoming content from IP addresses on a per-country basis. Minor improvements in other parts of the program include being able to make not only a recovery CD, but also a recovery USB key. Improvements have been made to the reputation-based detection system, rootkit detection, and spam blocking.

Kaspersky Internet Security 2011 comes with a free 30-day trial, and a one-year license retails for $79.95. Kaspersky AntiVirus 2011 also comes with a free 30-day trial, and its one-year license retails for $59.95. Full reviews of Kaspersky Internet Security 2011 and Kaspersky Anti-Virus 2011 will be available later today.
