First, my computer will not boot up and will not boot up in safe mode, but will boot up to the last known correct log-in (or whatever its called). It goes to load windows then I get an error message: isass.exe system error -or- Lsass.exe system error. I've been told its the sasser worm, and before I tried to reboot my computer and suspicious program was loading onto my computer and couldn't get it to stop. After the program was loaded onto my computer, I quickly deleted it and ran virius software (SpySweeper) - the results from the virus scan said something was found in memory and the computer needed to be restarted. From there the computer would not reboot giving me the isass.exe system error -or- Lsass.exe system error.
Once, I started the computer form the last known correct start-up after I couldn't boot up normally and re-boot in safe mode. I ran Spysweeper and same message that in order for the the scan results to take effect the computer must be restarted and from there it goes to restart but will not I get the same isass.exe system error -or- Lsass.exe system error.
Running - Windows XP
