The one thing I really am having a problem with is Virus Protection, I can't find ANY, I tried Avast and I can install it but then I get a compatability issue message. So I uninstalled that and tried AVG, well this was a good experience, I got a BSOD even before the installation had finished. The one that Microsoft says I should Install (Trend Micro PCCillin) does not work. It starts to install and then gets to Installing Firewall and then crashes and gets no further. So i currently have no Virus protection. As for a firewall the built in Windows Firewall has finally been changed and finally does its job the way a firewall Should (I don't know if this was true in previous builds), in beta 2 and Windows XP the firewall was set to close all ports. Whereas in this build (and maybe builds before) the ports are set to stealth mode. [color=#3333ff]Check [b]your firewall
This was my experience as well. I tried installing McAfee Enterprise and halfway through the installation I got the BSOD.
I haven't tried my copy of Symantec AV/Firewall or AVG.
