An interesting little tidbit from Gizmodo. Snow Leopard is performing checks on .pkg and .dmg files to make sure they don't have malware. This is interesting because this feature hasn't been mentioned in any of the Snow Leopard documentation up until this point. Also, we have to wonder if Snow Leopard will be downloading Malware definition files are regular intervals and doing all of that stuff we love on PCs.
Wonder if Snow Leopard can kill the malware that came with it on the torrent you installed it from?
