The pop up blocker is very neat. Probably the smartest and less obtrusive blocker I've used.

I'm unsure about the security panel as I use McAfee which provides its own...so I ended up with a lot of overlap. But otherwise, it too is a great feature.

One thing that annoyed me, and I posted a bug report, was that all my Windows Media Player 9 settings were lost in the update process. That sucked as all the songs I'd removed from the library, but not the hard drive reappeared. Hopefully that's going to be fixed Wink
