Recently, while traveling, I had to startup "Wireless Zero Configuration" in order to find the network where I was and logon to it. Now, I am back home and want to switch out of this -- my computer is running very slow. I have scanned using Webroot, Adaware and SpyBot and none found any problems w/ malware. My CPU usage reaches 100 percent all the time now with just a few programs open -- totally unlike before. I have tried turning off WZC, but I still have the high CPU usage problem. Tried a restore point, but that didn't fix either.  Please help.

I have a Dell Latitude 610 with a Dell Wirless 1450 Dual Band WLAN (802.11 a/b/g, 54 Mbps, and at home I connect to a Dell Wireless 2350 Broadband Router. Everything was fine until I left for this trip and had to use WZC to access a network. I have Win XP Pro SP3.
