Recently messenger error report keeps on popping every
couple of minutes. I cannot open windows messanger either
to find out what is wrong. This is disturbing and I feel
the impression as though something is trying to connect
to the net or something form the net is trying to connect
the computer.
What can be done to cure the problem? can this be a virus
or such? or it is just a bug?
Thanks for any help
Dedy,
By "messenger" do you mean "messenger service"?
There are at least three varieties of unwanted pop-ups, and the solutions vary
accordingly. Which specific type(s) are you seeing?
I. "Messenger Service" Pop-Ups
This will be a text only message, and will only hit you when you're online. A
Messenger Service pop-up can't contain a clickable link. The window will be
titled "Messenger Service".
This type of spam has become quite common over the past year or so, 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 Worm that still haunts the Internet. Install and use a decent,
properly configured firewall.

If you're using AOL, you'll either need to find a 3rd party firewall that is
compatible with AOL, or switch to a real ISP that is compatible with the real
Internet. This is because AOL is an on-line content provider that ignores
international networking standards in favor of its own proprietary products, and
has deliberately made its connection software incompatible with both WinXP's
built-in firewall and WinXP's Internet Connection Sharing feature. AOL's
proprietary connection applet is deliberately designed to preclude your
setting/adjusting any of its properties, to include enabling/disabling WinXP's
ICF and ICS.
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 (NetBIOS over TCP/IP). You'll have to follow the instructions
from firewall's manufacturer for the specific steps.
You can test your firewall at:

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.
II. Regular Browser Based Pop-Ups
This will be an HTML message, and will only hit you when you're online. A
browser based popup will probably contain clickable links. The window title
will vary.
Get the free Google Toolbar from <
http://toolbar.google.com/>. Hosts file
blocking (above) works on this problem also.
III. Adware / Spyware
This will be an HTML message, and can hit you when you're online, or offline.
An adware based popup will probably contain clickable links. The window title
will vary.
This is where you need a thorough adware / spyware scan, including CWShredder,
AdAware, Spybot S&D, and HijackThis, with expert advice to interpret the
HijackThis log.
Start by downloading each of the following free tools:
AdAware <

CWShredder <

CoolWWWSearch.SmartSearch (v1/v2) MiniRemoval

HijackThis <

LSP-Fix and WinsockLSPFix <

Spybot S&D <
http://www.safer-networking.org/index.php?page=download>
Stinger <
http://us.mcafee.com/virusInfo/default.asp?id=stinger>
Install and run Stinger.
<
http://us.mcafee.com/virusInfo/default.asp?id=stinger>
Create a separate folder for HijackThis, such as C:\HijackThis - copy the
downloaded file there. Spybot S&D has an install routine - run it. The other
downloaded programs can be copied into, and run from, any convenient folder.
Start by closing all Internet Explorer and Outlook windows, and running
CoolWebSearchSmartKillerMiniRemoval, then CWShredder. Have the latter fix all.
Next, run AdAware. First update it ("Check for updates now"), configure for
full scan (<
http://www.lavahelp.com/howto/fullscan/>), then scan ("Start" - "Use
custom scanning options" - "Next"). When scanning finishes, select everything,
and hit Next again.
Next, run Spybot S&D. First update it ("Search for updates"), then run a scan
("Check for problems"). Trust Spybot, and delete everything ("Fix Problems")
that is displayed in Red.
Then, run HijackThis ("Scan"). Do NOT make any changes immediately. Save the
HJT Log.

Finally, have your HJT log interpreted by experts at one or more of the
following security forums (and post it, or a link to your forum posts, here):

If removal of any spyware affects your ability to access the internet (some
spyware builds itself into the network software, and its removal may damage your
network), run LSP-Fix and / or WinsockXPFIx.

Paranoia comes from experience - and is not necessarily a bad thing.
