Testing anti-virus software is a tricky endeavour at the best of times, due to the inherent nasty nature of the test subject. For this anti-virus roundup, we asked independent anti-virus testing lab, AV-Test.org (www.av-test.org) to conduct the testing for us in their controlled environments. AV-Test.org has access to thousands of viruses, and is a respected anti-virus testing lab.

If the CCD is the brain of a digital video camera it is logical that three should be better than one. A single CCD has to deal with all colours together while a 3-CCD system divides the primary red, green and blue (RGB) colours to individual CCDs to give a much more precise and accurate picture. The result is a high quality image that is as good as any of the cameras tested - including the Sony DVD201E, which provided the benchmark for most of the others.
