Zonealarm originally made a name for itself through its free firewall software, but has since expanded its range to include a complete internet security package that includes virus protection and more.

The latest version of its most comprehensive package is Internet Security 2009, which builds on previous efforts by offering a revised interface and a new one-click Fix-it option.

The interface redesign was actually a little overdue but we’re pleased with the tidy new approach, which offers instant information on system security status along with the aforementioned single click to solve problems. You’ll also find useful additional information on this main page, including details about the latest threats and a system check to make sure you’re sufficiently protected.

Behind this new layout is a similar approach to tool configuration with which existing users will be familiar. For most of the program's sections this consists of a design based on using sliders that allow the user to make quick adjustments to security levels along with more detailed settings for fine-tuning.

This effectively splits the tools up into beginner and advanced views. While this is effective enough, we’d have liked to see some improvements here, perhaps in the form of step-by-step wizards to simplify more complex tasks.

Regardless, Zonealarm’s appeal in the past has come from the effectiveness of its firewall, and the fact that it can now combine this with excellent virus protection means that it’s one of the most formidable security suites on the market. Hourly updates keep the software bang up to date and if it’s peace of mind you’re after, there are few rivals out there that can offer this to a comparable extent.

Zonealarm does lack some useful extra features however. It omits tools such as an anti-phishing component, for which it points users towards the company's Forcefield application, which costs extra. It has also neglected to provide the backup or system tune-up tools that are becoming more common in programs such as this.

Despite these drawbacks Zonealarm is still an effective no-nonsense package that beginners will be happy to set and forget and that will leave experienced users feeling safe in the knowledge that they’re protected by some of the most impressive security expertise on the market. The price includes a year's cover for three home computers.
