I can't use my Zboard (gaming keyboard) or fingerprint reader for passwords, can't use microsoft sidewinder joystick, or Logitech wingman wheel. I can't download ANY patches for games or program updates. I can't download the critical update for windows explorer (which is designated for 64 bit but ALWAYS fails to install, with or without virus protection running.
All games crash at least once during play, Doom3, Farcry (wont install 64-bit update also), Need for Speed Most Wanted, Fear, Halflife 2 ,Time Shift demo ! Hey ! you asked...

Cant XP Pro x64 run any standard x86 antivirus? It supports emulated 32 bit apps so why not just run PC Cillin 32bit?

As antivirus runs at a device driver level it needs to be ported to work with a 64bit o/s. There are a few out there and the list is growing, below are a few I can remember;

Avast!
Nod32
AVG (but not Free AVG)
eTrust 7.1 (CA)
McAfee Enterprise 8.x
Symantec Corp
