I have Windows XP Pro with Norton Antirvirus installed and ZoneAlarm.
Yesterday I got message on starting Windows that a registry file had been changed and a successful recovery was made. Today when I started XP, I got to the XP pro screen where I am to select the appropriate User account. I got a system error message saying that the lsass.exe program was terminated, etc and then the sytem reboots in 1 minute. If I reboot in safe mode, I still get the same error and am not able to go to the Windows desktop. All the sasser (if it is the sasser worm) removal instructions start from the Windows desktop from which I am unable to go to. Please advise.
