Kaspersky Anti-Virus 2009 comes with very clean and easy to use interface. It consists of three main tabs - protection, settings and support. Kaspersky is a perfect tool for both home as well as advanced users. There are recommended settings for home users that can get you started right away, while more advanced users can fully customize the settings tab to suit their needs.

Few of Kaspersky’s capabilities are actually unique, but it combines a great range of useful features that are unmatched by most of its competitors. What this package lacks is a firewall but you are probably better of with a standalone one anyway.

Kaspersky Anti-Virus 2009 can scan at three different levels - Maximum, Normal and High speed. The system achieves accelerated scanning performance by only scanning new and changed files. Another plus is the ability of Kaspersky to change gears, meaning it will pause if other activities require additional resources or simply minimize its system resource needs depending on user activity.

Kaspersky updates their definitions on an hourly basis, the updates are done automatically and can be resumed if for some reason your connection goes bad.

Kaspersky Lab provides round-the-clock web, email and telephone based support services.

Kaspersky is an excellent choice in security software that comes with an excellent manual and online documentation. Besides being very thorough and reliable, it works fast and its very light on the system resources. It also runs on runs on Windows 2000, Windows XP, and Windows Vista. Kaspersky Anti-Virus 2009 is easy to install and does the job quietly and without annoying messages. The single license comes for close to 60$ and ten more for a three-user license, that of course is slightly more expensive than the competition but it is money well spent.
