Coverage goes only so far
Apple is dipping yet another toe into the anti-malware pond with a feature in the latest beta version of its forthcoming Snow Leopard operating system.
The protection was quietly added earlier this month to Snow Leopard 10A432, the most recent build of the new version of Mac OS X that is due for release this Friday, according to someone who has tested the feature and asked not to be identified because pre-release versions of Snow Leopard come with non-disclosure clauses. A separate Snow Leopard tester said the functionality is included in 10A421a, an even earlier build.
The feature causes users who try to install applications known to be malicious to receive a pop-up window warning that the file will damage the computer and should be moved to the Trash.
