nachi worn and reinstallation

I did a reformat and reinstallation of Win XP last night and this morning, when I hooked up the Net and download McAfee Virusscan, it told a few minutes later after installing the Windows Updates that it detected the Nachi worm and deleted it. Now, this is the second time this happened to me, and the first time was when I bought Win XP and installed it on a reformatted drive. I did some research on McAfee about the worm, but I still have one question: Is this worm present on my system when I reinstall Win XP or do I become instantly affected when I hook up to the Net? I didn't do anywhere on the Net except on MSN site and McAfee. I also have another hard drive hooked up as a slave, but it only contains music files. Could that be the culprit also?

You are instantly affected when you hook up to the Net unless:

1) you have a firewall enabled to block NetBIOS
2) and you have installed the patch that fixes the vulnerability

As Kent says...

It doesn't matter what site you do or don't connect to--connecting to the
Internet without even opening a web browser or other application will get
you nachi or blaster within seconds. It is coming from existing infected
machines searching for unprotected machines to infect.

You must either patch before connecting to the internet (or, in some cases,
even a large corporate network) or be sure that the firewall is enabled
before you connect to the Internet.

The world has changed with regard to a clean XP install.

Thanks for the responses. I was coming to the same conclusion myself.
