There is an extremely easy solution to this problem. Remove local administrative rights from users' PCs. There is absolutely no reason whatsoever for a user in a corporate environment to have local admin rights if they aren't actually a sysadm. In a home environment there is absolutely no reason for a user to be a local admin all the time. Remove this capability for the residential-grade OSs and make users utilize the Run As feature of XP and 2000. Better yet make this process automatic like in OS X. There is no reason in this day and age for users to need constant local admin access, if they need local admin access, period.
Justin PS==> IIRC Network Magazine, Network Computing, or some other such magazine echoed this exact sentiment in the most recent issue when they tested a couple dozed xIDS implementations. 100% of their spyware compromises were directly caused by local admin access. > -----Original Message----- > From: Matt Jonkman [mailto:[EMAIL PROTECTED] > Sent: Thursday, October 13, 2005 10:08 AM > To: Omar A.
