You might want to try :

1. Restart computer.
2. Hold or press f8 on the first screen you see.
3. Choose Last Known Good Configuration.

Hope that helps.

In order to remove Comodo though, you would need to be able to boot into Safe Mode or into normal mode. Trying to remove just the files in the Comodo folder will just lead to problems.

Do you have an XP CD? If so, boot to the recovery console. Once there, type the following:

expand d:\i386\lsass.ex_ c:\windows\system32\lsass.exe

This assumes your CD drive is D:, this overwrites the corrupted lsass.exe file. Try that and let us know what happens.

Is D: your CD-ROM? Try to browse to it. cd D: and post your results.

Actually, what type of Windows CD are you using? Some OEM's dont have the i386 folder in the default location.

Type D:

D:> cd i386
D:\i386> dir /p

Hit enter after each line break, then keep hitting spacebar as it scrolls down the files until you see lsass.ex_
