This is the infamous blaster worm. The first thing you should do with a new system upon connecting to the Internet is go to the Windows Update site and download all of the crittical updates listed. Then after rebooting, checking again to make sure there aren't any more listed. After which, you make a note to make monthly visits to this site if not more freequently.
Then you would be wise to download a copy of Mozilla ( http://www.mozilla.org ) to avoid some of the security issues related to Internet Explorer and Outlook Express. It's also a useful tool in preventing spyware from finding its way onto your system.
I just bought this computer 2 days ago. It's a Compaq presario. I'm not sure if the problem is with Windows XP, or Msn, or some other program. Here's what happens. When the desktop comes up on startup there is an error message that says that LSA Shell has encountered a problem and then it asks if you want to report the problem. Regardless of whether you try to report the problem or not, the next time that I try to get online through MSN a message comes up saying that NT Authority has issued an shutdown and then it does a countdown and the computer shuts down in 60 seconds. What's going on? Any help would be greatly, greatly appreciated. Thanks in Advance-Splanus
