The fact that you're here means your computer is working, but just in case anyone you know needs the instructions to disable McAfee: Boot the affected client into Windows Safe Mode with Networking (Hit F8 During the system boot phase.) Disable the McAfee McShield service by opening the Registry Editor (regedit.exe), and set the McAfee McShield service to the Disabled startup type: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\McShield\Start=4. Once you've rebooted in to normal mode you can rollback definitions from the McAfee gui.
