Solve : msls51.dll error help required?

Hi I have a HP laptop with Windows XP INSTALLED. I have McAfee installed along with Malware bytes on the SYSTEM. Recently malwarebytes had found a few trojan and malicious software which were quarantined (this list also included the msls51.dll file which was quarantined). Yesterday after a RESTART I encountered a few error messages:
"lsass.exe - Unable to run Component
The application has failed to start because msls51.dll was not found. Re-installing the application MAY fix this problem"

the most frequent message which pops up is "msls51.dll was not found"
I also get another message before the desktop background appears which is " userinit.exe - Unable to run Component".

I only get the background appearing (no toolbar, no desktop icons) once windows starts and that's it.
I can access the task manager through ctrl+alt+del and try and run tasks through it. I tried running Ccleaner but it does not allow me to run it. I also tried downloading Superantispyware but it does not seem to load in the normal mode. havent tried it in safe mode though. I tried downloading Combofix and installing it in safemode but the system has got hung up.

I have tried to do a system restore to a previous date using task manager but that doesnt seem to work. i have also tried to run malwarebytes and spybot in safemode but they dont seem to clean up my laptop.

I hope yopu can help me clean up my system as I dont want to reformat my disk and reload everything back.
Thanks in advance for the help
