Greetings --
Why would you pay extra for something ("Windows XP Professional
2000") that does not exist? Doesn't seem particularly wise, from a
business point of view. :-} Do you have WinXP Professional, or Win2K
Professional? In this case, though, your specific operating system
doesn't really matter. Additionally, Microsoft doesn't send updates
to anyone, ever. If you've been installing something you think
Microsoft sent, you've been installing viruses. If you're going to
rely upon this PC for your business needs, you really need to learn
something about computer security.
To get you started:

For your specific current issues:
Pop-ups:
Does the title bar of these pop-ups read "Messenger Service?"
This type of spam has become quite common over the past several
months, and unintentionally serves as a valid security "alert." It
demonstrates that you haven't been taking sufficient precautions while
connected to the Internet. Your data probably hasn't been compromised
by these specific advertisements, but if you're open to this exploit,
you may well be open to other threats, such as the Blaster Worm that
recently swept cross the Internet. Install and use a decent,
properly configured firewall. (Merely disabling the messenger
service, as some people recommend, only hides the symptom, and does
little or nothing to truly secure your machine.) And ignoring or just
"putting up with" the security gap represented by these messages is
particularly foolish.

Oh, and be especially wary of people who advise you to do nothing
more than disable the messenger service. Disabling the messenger
service, by itself, is a "head in the sand" approach to computer
security. The real problem is _not_ the messenger service pop-ups;
they're actually providing a useful, if annoying, service by acting as
a security alert. The true problem is the unsecured computer, and
you've been advised to merely turn off the warnings. How is this
helpful?
The "Microsoft" patches:
What you received is either a very common malicious hoax or the
output of a computer infected by one of several wide-spread, mass
emailing worms. The most widely-known are:
W32.Swen.A_mm
http://securityresponse.symantec.com/avcenter/venc/data/[email protected]
W32.Dumaru_mm
http://securityresponse.symantec.com/avcenter/venc/data/[email protected]
W32.Gibe_mm
http://securityresponse.symantec.com/avcenter/venc/data/[email protected]
Microsoft never has, does not currently, and never will email
unsolicited security patches. At the most, if, and only if, you
subscribe to their security notification newsletter, they will send
you an email informing you that a new patch is available for
downloading.

How to Tell If a Microsoft Security-Related Message Is Genuine
http://www.microsoft.com/security/antivirus/authenticate_mail.asp
Any and all legitimate patches and updates are readily available
at
http://windowsupdate.microsoft.com/. (Notice that this is the true
URL, rather than the bogus one that may have been contained in the
email you received.) Any messages that point to any other source(s) or
claim to have the patch attached are bogus.
You're receiving these emails because your email address is in
the address book of someone infected with a worm, and/or because you
posted your real email address somewhere on-line, either in a forum
accessible to the public and spambots, such as Usenet, or on an
untrustworthy web site that subsequently sold your address as part of
a mailing list. One thing you can do is notify _everyone_ with whom
you've ever corresponded via email that one or more of them may be
infected with a mass emailing worm, and should take the appropriate
steps.
There's probably no way of blocking all of the bogus messages, but
you can greatly reduce the number you get by creating a rule, based
upon the most commonly used subject lines, to delete the emails from
the server without ever downloading them.
