Windows Defender, a security application built in to windows Vista, has again come in for criticism from security experts.
Researchers from Enex TestLab, an independent testing facility, tested Windows Defender and found that it only blocked 46 per cent of current spyware threats.
Such kind of tests carried by a competitor directly or indirectly is not worth considering. Tests conducted by reputed organisations like iCSA Labs, Westcoast labs which are neutral should be trusted.
