G Data InternetSecurity 2010

If all you're concerned about in security suite is signature detection, then G Data SecuritySuite 2010 is a safe bet. Combining two engines (AVAST and BitDefender), G Data SecuritySuite 2010 has achieved some of the highest detection rates on independent tests performed by AV-Test.org. However, the suite does have a larger overall footprint than and consumes more system resources than some of its competitors. Those with slightly older hardware may find this problematic. Pricing is attractive - G Data SecuritySuite 2010 is one of the cheapest, at $29.95 for one PC or $39.95 for up to three.

G Data SecuritySuite 2010 uses two antivirus engines, AVAST and BitDefender. Standalone, both engines offer good detection and when combined each picks up where the other might let off. In theory, this could translate into faster signature releases (G Data offers hourly updates) and overall improved heuristics.

Historically, G Data has consistently had top detection rates on independent tests from AV-Test.org. However, test results in a zoo environment may not reflect actual performance against in-the-wild threats via the Web. Even the best signature detection technologies are struggling to keep up with the volume of today's threats - tens of thousands of new malware variants each day. Thus, additional security features become increasingly important to narrow the gap in protection.

For Web-specific protection, the G Data WebFilter installs a browser toolbar designed to block pop ups and other active content from websites. Because it's a toolbar, the functionality can change (or be broken) when updating an existing browsers or if switching to a new one. Overall, the feature is inferior to the virtualization and reputation systems offered by competing security suites.

The firewall is adequate, as are email and IM controls, though none of these features distinguish themselves in any way.
