We just started receiving a pop up labeled "Messenger service" that claims we
have 55 critical system errors and should immediately go to:
www.regfixit.com and install registry update.
We ran all of our anti virus software and nothing came up.
1. Is this just a pop up to sell us something we don't need?
2. How do we get rid of it?
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 couple of
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?

Neither adware nor spyware, collectively known as scumware,
magically install themselves on anyone's computer. They are almost
always deliberately installed by the computer's user, as part of some
allegedly "free" service or product.
While there are some unscrupulous malware distributors out there,
who do attempt to install and exploit malware without consent, the
majority of them simply rely upon the intellectual laziness and
gullibility of the average consumer, counting on them to quickly click
past the EULA in his/her haste to get the latest in "free" cutesy
cursors, screensavers, "utilities," and/or wallpapers.
If you were to read the EULAs that accompany, and to which the
computer user must agree before the download/installation of the
"screensaver" continues, most adware and spyware, you'll find that
they _do_ have the consumer's permission to do exactly what they're
doing. In the overwhelming majority of cases, computer users have no
one to blame but themselves.
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.
