Hello,Cayman,
You have Blaster/MSBlast/Lovesan-call it what you
will.Welcome to the darkside of computing.It's an RPC
exploit.That means,it will enter your computer through
a "hole" just because you are online.
Enable the XP firewall,if you can-Blaster does prevent
this,however,so if you cannot turn it on because the
settings are inaccessible/greyed out etc..go straight to
the following site:
Fix available here:
http://www.norman.com/Virus/Virus_removal_tools/11359/en
You could also run Stinger (Best saved to
floppy):
stinger:
http://vil.nai.com/vil/stinger/
Disconnect from the Internet,if you can,while you run the
fixes.
After either of these devices have deleted the Blaster
files,enable the firewall immediately.Then run a full
online scan of your O.S. at any of the locations below:
Trend:

McAfee:

Panda:

If offered an option to clean or delete,opt for
delete.
I am sorry your first day on the net was such a baptism
of fire.
