I keep getting this pop up message from Messenger Service stating that my
computer has been corrupted and I need to go to a website immediately to
clean my computer - for real or not?
It's a scam, plain and simple. It's from a very unscrupulous
"business." They're trying to sell you patches that Microsoft provides
free-of-charge, and using a very intrusive means of advertising. It's
also demonstrating that your PC is very unsecure.
This type of spam has become quite common over the past few years,
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 most
definitely open to other threats, such as the Blaster, Welchia, and
Sasser Worms that still haunt 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.

Whichever firewall you decide upon, be sure to ensure UDP ports 135,
137, and 138 and TCP ports 135, 139, and 445 are all blocked. You may
also disable Inbound NetBIOS over TCP/IP). You'll have to follow the
instructions from firewall's manufacturer for the specific steps.

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?
There are several essential components to computer security: a
knowledgeable and pro-active user, a properly configured firewall,
reliable and up-to-date antivirus software, and the prompt repair (via
patches, hotfixes, or service packs) of any known vulnerabilities.
The weakest link in this "equation" is, of course, the computer
user. No software manufacturer can -- nor should they be expected
to -- protect the computer user from him/herself. All too many people
have bought into the various PC/software manufacturers marketing
claims of easy computing. They believe that their computer should be
no harder to use than a toaster oven; they have neither the
inclination or desire to learn how to safely use their computer. All
too few people keep their antivirus software current, install patches
in a timely manner, or stop to really think about that cutesy link
they're about to click.
Firewalls and anti-virus applications, which should always be used
and should always be running, are important components of "safe hex,"
but they cannot, and should not be expected to, protect the computer
user from him/herself. Ultimately, it is incumbent upon each and
every computer user to learn how to secure his/her own computer.
