I have two laptops, both running Ad Aware and Symantec Norton...

Two days ago, the one the kids play on started giving me the message lsass.exe - object not found...its OS is Win XP Home that was supposedly patched to SP2..

The only choice I had on the given screen was to click 'OK' and let it reboot....it wouldn't even allow a safe mode start or anything...EVERYTHING came back to the same spot...

In addition, it changed my administrator password (which was 'enter'), again, always ending up back at the 'OK' button. I even tried several programs to override the password, only to get back to the same point.

Short story made long - sorry - I ended up reinstalling Win XP (Home Edition) into a new directory (WINDOWS2)...on the same drive...

I then patched Win XP Home and ran several 'tools' and all say I have no virus.

I know that something is wrong - like a virus - because several times a 'blue screen' appeared with a funky, smudgy 'Windows XP' logo in the upper right...and it would say 'Re-Setting Start Up'..... then eventually back to the 'OK button'....which I would have click to get past...then auto-reboot...

I personally scanned that drive at least every other day with Ad Aware AND Norton - but somehow it didn't catch it -....is this the Sasser worm from years ago?

What should I do now?

Is this something you can help me with?

I would like to get back to the original XP Boot up (WINDOWS)...is that possible?

Any help would be greatly appreciated!!
