OK, this has been bugging me all morning, and before I do a wipe and reinstall windows I am wondering if anyone can offer some suggestions for getting rid of this annoying virus/malware problem. I've got a new machine which is locking me out of the task manager and regedit (error msg - restricted by admin) and I have narrowed it down to lsass.exe which I have managed to get rid of it in safemode with malwarebytes. The problem I have is although I can then get into the registry and task manager, as soon as I try to log in normally the files have recreated themselves and the problem persists.
What I want to know is where is this file being recreated from? I have also found reg entries for dido.exe and akaro.exo which seem to be linked, but I cant find any files which when deleted remove lsass permanently.

You mean the Microsoft Local Security Authentication Server service?
Be wary as there is a trojan which has a process called Isass (the capial I in the default windows font looks the same)

It may be the W32.Sasser worm, see here for removal instructionsW32.Sasser.Worm Removal - Removing Help | Symantec
penfold - have you tried SuperAntispyware to remove the trojan

Nope, not unless MS creates a reg key which blocks you frmo accessing the registry and Taskmanager

- Rep Power
did you disable system restore before running malwarebytes?

Yup, although I forgot at first.

Got it sorted now. The only thing I did differently was to also run an AVG removal software as the lsass.exe was showing as associated with AVG(even though AVG has never been installed) and I remember seeing some spyware like this before.
Thanks for those with the suggestions anyway.
