UH... when you install Windows7, it does FLAG a warning about the lack of an Antivirus program and WILL/CAN open a Window to download an Antivirus program, besides Microsoft's.
So I call the "Security expert" as fud.
Yeah, UAC is dialed back a bit... but the USER can make it as bad as Vista... and oh yeah, vista's UAC was such retarded crap that most people TURNED IT OFF when they can or find out that they could!
UAC (in vista) is such garbage that it POPs up with when doing such simple things like Device manager, Display settings, rename a desktop icon, etc... it gets old very very fast.
With Win7, it can be left on with minimal bother. Still stupid thjavascript: void(0);at there isn't a CHECK BOX to remember what the program is like firewalls do or SpyBot's tools.
