lsass.exe- Sasser Worm

Specs: Windows XP, UNKNOWN
Hi everyone,

Hoping someone can help me. I'm fairly computer illiterate...

I have just borrowed a laptop from a friend and today when I went to turn it on I got the message that there was a problem with lsass.exe.

From reading a little on forums it seems that the computer may have developed the Sasser Virus.

The problem with all the posts on the forums is that most of them are relying on the user having a fair bit of knowledge about hardware etc whereas I only know what to do after getting to the main XP screen/desktop.

Can someone help with a dumbed down version of how to fix? I can't run the computer at all, not even in safe mode.

Not sure about the model no. of the computer, but it is a Dell if this helps...

I think you should update your antivirus as in some cases it may be infected with a variant of torjan spyware which steals information from your computer. if you don't have any antivirus installed then visit the following link to find some effective antivirus software for your needs.

You'll need a tool like avast virus cleaner to clean the virus. Are you able to logon to the desktop? If so, download the file to a usb flash drive and run the program from there.

thanks for the help syslock but I can't get to the desktop. This message appears before the log-in screen...

Any further suggestions? I have a copy of XP on CD but not the same as the one that's already loaded... if I do a system repair with the XP disk will that stuff it all up?

Also, how do I do a system repair?

you will need a xp home disc if that is what is installed or vice versa with the xp pro. You cannot mix and match. Here is how to do a repair install:

I don't think you have a virus. Google for the error and look at the link I provided.

since you have an xp cd you could try this:

I guess you have nothing to lose, by trying this before a repair install.

I didn't think you could get to the desktop which is why I asked. I would try one of two things since the file is responsible for logging onto windows.

To ensure it isn't a virus, create a bootable cd that will allow you to scan your hard drive. UBCD4Win is a great tool to have around and can easily be created with a cd burner and software such as roxio or nero. Once created you can run the virus scan utilities once booted.

If it isn't a virus, try using the recovery console to restore a new copy of lsass.exe to your drive.
