Symantec Vista White Paper Links to PatchGuard Crack
Since it’s apparently only found in 64-bit versions of Vista (and therefore only an extremely small percentage of current machines will ever see it), I’ve yet to hear much about PatchGuard other than Symantec’s insistence that it’s going to severely compromise the ability of other security vendors to protect users by preventing low-level access to the Windows kernel.
I’m sure we can expect a law suit from Microsoft any day now…
