Need serious help with a laptop. Running Windows XP Professional.

Sorry if this is in the wrong place. I am kind of lost on a site like this.

Our 11 year old daughter went on the laptop and got on the internet. We don't really know what happened after that. Now, everytime you turn it on, and log in, it will bring up the desktop and then you get the error message that ISAS.EXE must close, send error report or not?
Then, the blue screen of death. When the blue screen of death comes up, the only thing I can read before it shuts down is "beginning memory dump".

Can anyone tell me what to do and how to do it? I have tried ESC at the beginning of the load up and also ctrl-alt-del to get into the directory to view it, but, the computer always boots right on up to the log in screen. Any help would be appreciated.
We are not able to send the error report, due to the speed of which the blue screen of death takes over the laptop.

 

isas.exe is a trojan downloader as shown here in this article

Can you boot into safe mode? If so boot into safe mode and run the malware thread here.

Ok. Now, another stupid question: How do I do that? Boot in safe mode, I mean. Fair warning: You are probably talking to the most computer illiterate person on the planet. I understand the trojan program thing, but, after that, you lost me.

 

If the computer is running, shut down Windows, and then turn off the power
Then turn the computer on.
Start tapping the F8 key immediately. The Windows Advanced Options Menu appears. If you begin tapping the F8 key too soon, some computers display a "keyboard error" message. To resolve this, restart the computer and try again.
Ensure that the Safe mode option is selected.
Press Enter.

 

Oops, I was gonna correct my earlier post, but TimW beat me to it .

 

Ok, I made it that far, and managed to go into safe mode with networking and now I am looking at a blank screen.

 

Because of the way lsas.exe is written, it's easy to confuse with isas.exe.
Your system may be infected with the W32.Sasser worm.
W32.Sasser Removal Tool

 

Ok, so, this is probably a worm and it is a lower case L (l) sas, right? Not I? I have managed to get pretty far into this now. Am In the process of using the AKO free pest control and spyware removal programs. I will probably have the husband use the sasser thing tonight when he gets home. I appreciate your help!!!!
