Via the Grand Stream Dreams blog: Symantec seems to came out with an "updated" version of UAC.
My opinion? In the short term solutions like this are effective for at least two reasons: (a) they are to particular for "bad guys" to care about (why should they but effort into something which is used by less than 0.01% of the market?) and (b) the people who start to use it first are the power-users who can make more sense out of the message. In the long run this won't solve the dancing bunnies problem.
