On two of my WinXP boxes, ZoneAlarm found and deleted "Win32.Worm.Socks.BW". Thereafter, the login mode reverted to the classic where you have to type in your username and password. I tried resetting the checks (which were already properly set) at: Control Panel -> User Accounts -> Chenge the way users log on or off and it didn't help. Thanks for your help. Mike.
