Thank everyone for giving me suggestions.
Thank Jim that I downloaded Keyfinder and found my
production key.
Thank Tumbleweed and Kelly about the virus information.
About the virus in my computer, the thing is that I
installed AVG 6.0 in my computer. It detected the virus
and said it removed the virus. But I used Symantec
website's online Virus Detection to scan my computer. It
lists: "C:/windows/systems32/ntvdscm.dll is infected with
Keylogger.Trojan; C:/windows/systems32/ntvdscm.exe is
infected with PWSteal.Trojan; C:/Documents and
Settings/Xiaoping/.jpi_cache/jar/1.0/demo.jar-2e26db2e-
6d7d4547.zip is infected with Trojan.ByteVerify"
I don't know much about the virus. that is why I want
format the whole computer to remove it. Any further
suggestion?

Are you running a firewall? If not its a waste of time removing these
because they(or something similar) will just come back.
http://securityresponse.symantec.com/avcenter/venc/data/keylogger.trojan.html
tells you how to remove keylogger
The fact that you have Trojan.ByteVerify means you havent been keeping up to
date with windows updates.
Is it the same for AVG, are you running the latest?
I would suggest, in the following order you;
print out removal instructions for these viruses/trojans you mention(Found
via google searches).
Download the latest version of avg.
Download the latest version of adaware and spybot.
Download but do not install zone alarm free version.
Disconnect from net (physically), empty wastebasket, temp files, IE cache.
Run adaware, spybot, avg.
Follow removal instructions to see if anything is left.
install zone alarm free version.
connect to net and see if anything suspicious asks zone alarm if it can
access the net.
run symantec online check and see what it says.
This will probably take about an hour, a lot quicker than reinstalling XP,
especially if you factor in that when you reinstall XOP you'll then have to
install *all* the windows updates all over again (assuming you did install
some) .
Now keep up to date with firewalls.
FWIW although Norton gets bad press here I have never had a virus get
through Norton AV, OTOH my daughters PC (which she hadnt been keeping up to
date with AVG I admit) did get some. If you want to get Norton, valid copies
of Norton can be had much cheaper on ebay. these are OEM versions and dont
come with a manual but its not really needed.
But these days a firewall is just as needed as a virus scanner
