Explorer.exe Application Error

Help,

My kids got Napster for Christmas and have now downloaded a very nasty virus disguised as an alert saying that my computer is infected with spyware and "click" here to fix it.

Right now, I can only get to my wallpaper, it won't load any icons. I can get into safe mode but the only thing I can do is bring up Task Manager. The following happens when I reboot:

Explorer.exe Application Error
The application failed to initialize properly (0xc0000005).

I'm using Windows XP Home Edition on a Dell Machine. I have ad aware on there now, but when I try and run it via Task Manager I get the same error message. I had Panda Anti virus on, but I deleted it about two weeks ago becuase of some conflicts with the firewall.

Anybody have any suggestions, knowing that I can only use Task Manager or a Cmd prompt??

Thanks....

 

Yes, my desktop computer has been taken over by the dark side.

Thanks..

 

Well, I did and I get the same response...
