On my new Dell laptop with windows XP, this worm showed up when I ran the Norton anti-virus scan. I was able to run the symantec cleaner to delete it. Could this worm have been on the computer when I got it?

Why do a lot of worms start with "w32"?

In my opinion, it is unlikely that it came with your laptop. This worm has only been around for about a month.

It uses the DCOM RPC vulnerability in some unpatched Microsoft OS. If you do not have a firewall and the patch for XP, then about as soon as you got online, it probably got on your machine.

Here is some good information from Symantec click here

Does this help?

I have Norton which was activated from the start. But Norton didn't advise me that it would check for virus's until after I used e-mail. Then It advised me that there were 20 new virus's it was looking for, and thats when this one showed up. I figured I probably got it from my one and only e-mail received in a brand new hotmail account. Sheesh, What are the odds of getting a new computer, a new e-mail acct, AND getting a virus on the first e-mail. Pretty Bad. I need to run the windows update which has about 36 mb of patches and a bunch of critical updates. When I can leave my computer alone, i'll set it to download all of that for a couple of hours. (first thing tomorrow).

Thanks for the information. I briefly looked at that link already when I downloaded the clean up utility the other day. Lots of good info. there.

The worm isn't a virus, although NAV will detect it after it's installed itself. You need a firewall to protect you against this kind of threat.

You could be one of the most unlucky users in the world. But let me add this, it is my understanding this worm doesn't come from e-mail but throught your internet connection. You said you are using Norton as an antivirus, but are you also using Norton's firewall?

Great. If you do not have a firewall, I would suggest you get one. The XP firewall only monitors incoming traffic and if you got Welchia worm, apparently not all that well. A stand alone firewall will monitor both incoming and outgoing traffic.

You can download Zone Alarm firewall here and it is free.
