Hi Matthew (with two t's
) - There are currently two classes of things
going on that are causing people popup difficulties. If you get popups even
when your browser is not connected to the Internet with a title bar reading
"Messenger Service", then these are most likely due to open NetBios TCP
ports 135, 139 and 445 and UDP ports 135, 137-138 and a UDP port in the
range of 1026-1029.. You really need to block these with a firewall as a
general protection measure. You can stop the popups by turning off
Messenger Service; however, this still leaves you vulnerable. If you have
an NT-based OS such as XP or Win2k, you should probably also specifically
block TCP 593, 4444 and UDP 69, 139, 445, and install the very important
824146 patch from MS03-039, here:
http://support.microsoft.com/default.aspx?kbid=824146 to block the Blaster
worm as well as several other parasites.
See: Messenger Service Window That Contains an Internet Advertisement
Appears
http://support.microsoft.com/?id=330904 which identifies reasons to
keep this service and steps to take if you do.
You can test your system and follow the 'Prevention' link to get additional
information here:
http://www.mynetwatchman.com/winpopuptester.asp Unless you have very good
reasons to keep this active, it should be turned off in Win2k and XP. Go
here and do what it says:
http://www.itc.virginia.edu/desktop/docs/messagepopup/ or, even better, get
MessageSubtract, free, here, which will give you flexible control of the
service and viewing of these messages:
http://www.intermute.com/messagesubtract/help.html Recommended.
(FWIW, ZoneAlarm's default Internet Zone firewall configuration blocks the
necessary ports to prevent this use of Messenger Service. I don't know the
situation with regard to other firewalls.)
Messenger Service is not per se Spyware or something that MS did wrong - It
provides a messaging capability which is useful for local intranets and is
also sometimes (albeit nowdays infrequently) used by some applications to
provide popup messages to users. However, it can also be (and now frequently
is) used to introduce spam via this open NetBios channel. For a single user
home computer, it normally isn't needed and can be turned off which will
eliminate the spam popups. This DOESN'T, however, remove the vulnerability
of having these ports open, when in fact they aren't needed, since they can
be perverted in other ways as well, some of which can be much more damaging
than just a spam popup.
If you're getting a lot of popups while surfing, then the following may be
useful:
#########IMPORTANT#########
Before you try to remove spyware using any of the programs below, download
both a copy of LSPFIX here:
http://www.cexx.org/lspfix.htm
AND a copy of Winsockfix for W95, W98, and ME
http://www.tacktech.com/pub/winsockfix/WinsockFix.zip
Directions here:
http://www.tacktech.com/display.cfm?ttid=257
or here for Win2k/XP
http://files.webattack.com/localdl834/WinsockxpFix.exe
Info here:
http://www.spychecker.com/program/winsockxpfix.html
Directions here:
http://www.iup.edu/house/resnet/winfix.shtm
The process of removing certain malware may kill your internet connection.
If this should occur, these programs, LSPFIX and WINSOCKFIX, will enable you
to regain your connection.
NOTE: It is reported that in XP SP2, the Run command netsh winsock reset
will fix this problem without the need for these programs. (You can also
try this if you're on XP SP1. There has also been one, as yet unconfirmed,
report that this also works there.) Also, one MS technician suggested the
following sequence:
netsh int reset all
ipconfig /flushdns
See also:
http://windowsxp.mvps.org/winsock.htm for additional XPSP2
info/approaches using the netsh command.

Show hidden files and run all of the following removal tools from Safe mode
or a "Clean Boot" when possible, logged on as an Administrator. BEFORE
running these tools, be sure to clear all Temp files and your Temporary
Internet Files (TIF)(including offline content.) Reboot and test if the
malware is fixed after using each tool.
HOW TO Enable Hidden Files
http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2002092715262339
Clean Boot - General Win2k/XP procedure, but see below for links for other
OS's (This for Win2k w/msconfig - you can obtain msconfig for Win2k here:
http://www.3feetunder.com/files/win2K_msconfig_setup.exe ):
1. StartRun enter msconfig.
2. On the General tab, click Selective Startup, and then clear the 'Process
System.ini File', 'Process Win.ini File', and 'Load Startup Items' check
boxes. Leave the 'boot.ini' boxes however they are currently set.
3. In the Services tab, check the "Hide All Microsoft Services" checkbox,
and then click the "Disable All" button. If you use a third party firewall
then re-check (enable) it. For example, if you use Zone Alarm, re-check the
True Vector Internet Monitor service (and you may also want to re-check
(enable) the zlclient on the Startup tab.) Equivalent services exist for
other third party firewalls. An alternative to this for XP users is to
enable at this time the XP native firewall (Internet Connection Firewall -
ICF). Be sure to turn it back off when you re-enable your non-MS services
and Startup tab programs and restore your normal msconfig configuration
after cleaning your machine.
4. Click OK and then reboot.

Sometimes the tools below will find files which they are unable to delete
because they are in use. A program called Copylock, here,
http://noeld.com/programs.asp?cat=misc#CopyLock can aid in the process of
"replacing, moving, renaming or deleting one or many files which are
currently in use (e.g. system files like comctl32.dll, or virus/trojan
files.)" Another is Killbox, here:
http://www.downloads.subratam.org/KillBox.zip
A third which is a bit different but often useful is Delete Invalid File,
here:
http://www.purgeie.com/delinv.htm which handles invalid/UNC
file/folder name deleting, rather than the in use problem
Download and run Stinger.exe, here:

Boot to Safe mode with Network Support (HowTo here:
http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001052409420406)
or a Clean Boot as above.
Download sysclean.com , from Trend Micro, here:
http://www.trendmicro.com/download/dcs.asp along with the latest released
pattern file, here:
http://www.trendmicro.com/download/pattern.asp Be sure
to read the "How-to" info here:
http://www.trendmicro.com/ftp/products/tsc/readme.txt
(You might also want to get Art's updater, SYS-UP.Zip, here for future
updating of these:
http://home.epix.net/~artnpeg/). The updater files plus a
short tutorial on using them and SysClean are also available in one package
here:
http://www.ik-cs.com/Programs/virtools/SYSCLEAN UTILITY.exe (If you
download and use the updater from the beginning, it will automatically
handle downloading the other files.)
NOTE: You can get a somewhat more current interim pattern file, the
Controlled Pattern Release, here and manually unzip it to your SysClean
folder:
http://www.trendmicro.com/download/pattern-cpr-disclaimer.asp
(Sorry, but the Updater won't get this one for you.) Look for the lptxxx.zip
file after you agree to the terms.
Place them in a dedicated folder after appropriate unzipping.

If you're using WindowsME or WindowsXP, SysClean (and the other cleaning
tools below) may find infections within Restore Points which it will be
unable to clean. You may choose to disable Restore if you're on XP or ME
(directions here:
http://vil.nai.com/vil/SystemHelpDocs/DisableSysRestore.htm) which will
eliminate ALL previous Restore Points, or alternatively, you can wait until
cleaning is completed and then use the procedure within the *********'s
below to delete all older, possibly infected Restore Points and save a new,
clean one. This approach is in the sprit of "keep what you've got" so that
you can recover to an at least operating albeit infected system if you
inadvertently delete something vital, and is the approach I recommend that
you take.
Read tscreadme.txt carefully, then do a complete scan of your system and
clean or delete anything it finds.
Reboot and re-run SysClean and continue this procedure until you get a clean
scan or nothing further can be cleaned/removed.
Now reboot to normal mode and re-run the scan again.
This scan may take a long time, as Sysclean is VERY extensive and thorough.
For example, one user reported that Sysclean found 69 hits that an
immediately prior Norton AV v. 11.0.2.4 run had missed.
Popups - The best way to start is to get Ad-Aware SE Personal Edition, here:
http://www.lavasoftusa.com/support/download/. UPDATE, set it up in
accordance with this:
http://forum.aumha.org/viewtopic.php?t=5877 and run
this regularly to get rid of most "spyware/hijackware" on your machine. If
it has to fix things, be sure to re-boot and rerun AdAware again and repeat
this cycle until you get a clean scan. The reason is that it may have to
remove things which are currently "in use" before it can then clean up
others. configure Ad-aware for a customized scan, and let it remove any bad
files found.....
Then, courtesy of NonSuch at Lockergnome, open Ad-aware then click the gear
wheel at the top and check these options to configure Ad-aware for a
customized scan:
General> activate these: "Automatically save log-file" and "Automatically
quarantine objects prior to removal"
Scanning > activate these: "Scan within archives", "Scan active processes",
"Scan registry", "Deep scan registry," "Scan my IE Favorites for banned
sites," and "Scan my Hosts file"
Tweaks > Scanning Engine> activate this: "Unload recognized processes during
scanning."
Tweaks > Cleaning Engine: activate these: "Automatically try to unregister
objects prior to deletion" and "Let Windows remove files in use after
reboot."
Click "Proceed" to save your settings, then click "Start." Make sure
"Activate in-depth scan" is ticked green, then scan your system. When the
scan is finished, the screen will tell you if anything has been found, click
"Next." The bad files will be listed. Right click the pane and click "Select
all objects" - This will put a check mark in the box at the side, click
"Next" again and click "OK" at the prompt "# objects will be removed.
Continue?"
Courtesy of
http://www.nondisputandum.com/html/anti_spyware.html: HINT: If
Ad Aware is automatically shut-down by a malicious software, first run
AWCloak.exe,
http://www.lavasoftnews.com/downloads/AAWCloak.exe, before
opening Ad Aware. When AAWCloak is open, click “Activate Cloak”. Than open
Ad Aware and scan your system.
Another excellent program for this purpose is SpyBot Search and Destroy
available here:
http://security.kolla.de/ SpyBot Support Forum here:
http://www.net-integration.net/cgi-bin/forums/ikonboard.cgi. I recommend
using both normally. Update before starting, then after fixing ONLY RED
things with SpyBot S&D, be sure to re-boot and rerun SpyBot again and repeat
this cycle until you get a clean "no red" scan. The reason is that SpyBot
sometimes has to remove things which are currently "in use" before it can
then clean up others.
Then, there are a variety of third party "Popup Killers" available. I
normally use AdShield, which, if you maintain its Block List every now and
then, almost totally stops this. In addition, it stops a variety of
ads/banners/etc. (particularly spyware like doubleclick) on pages I access.
This is probably all you'll need; however, I've also investigated a program
called webwasher which appears to be very good, but decided that AdShield
was sufficient. At the bottom of this post, you'll find a list provided
courtesy of bc_acadia of a number of free popup blockers with links.
****** NOTE: As of 28 Apr 03 AdShield appears to have partnered with a new
reseller, and AdShield is no longer free. There is a trial version of
AdShield3; however, IMO it is seriously crippled in not being able to import
or export block lists and I think for reasonable utility one would have to
go to the full version. While I don't normally recommend non-free software,
I personally will continue to use AdShield3, since I think it is the best
currently available combined Popup/Ad/Malware blocker, but you should be
aware of the fact that it now costs, ($29.95), whereas the earlier versions
upon which I based my original recommendation were free, although not nearly
as capable as the AdShield3 release. I've included below links to both the
older free version and the new paid version. You'll have to investigate and
make your own choice in the matter. *******

http://www.webwasher.com - Webwasher
For WinXP users, Service Pack 2 has a built-in popup stopper which at first
look appears to be fairly effective.
Additionally, some people have recommended Popup Stopper and PopupBuster,
but they have also been reported or experienced to cause perceived problems
for some people with "normal" links in IE6 such as Google search results and
links from OE. Some proponents of PopupBuster assert, however, that this is
normal operation for this program under certain circumstances which can be
overridden if necessary. YMMV Another "Proxy" type blocker similar to
Webwasher and Proxomitron but supposedly a bit easier to configure is
Privoxy here:
http://www.privoxy.org/
Also, the free Google Tool Bar has a builtin popup blocker which is fairly
effective.
A very clever alternative approach to general ad (vice Popup) blocking is
outlined here:
http://www.sherylcanter.com/articles/oreilly_20040330_HostsPac.php
and here:
http://s91363763.onlinehome.us/BlackHoleProxy/index.html
The approach is similar to that used in eDexter, but improved. I've tried
it, and it does work as advertised. (<groan> - sorry 'bout that!)
Probably should only be considered by more knowlegable users, as it's a
little complicated to set up using the directions given if you don't already
know a bit. (It also has some tendency to block some things you'd rather it
didn't at times if PAC files are used instead of the HOSTS file due to its
use of regular expressions for blocking definitions without some tuning.)
There is additonal information about setting up and using AdShield, and
about using the Restriced Zone (and an additional list) here:
http://www.mvps.org/winhelp2002/hosts.htm
Lastly, ZoneAlarmPro3/4 has added provisions for stopping adds/popups,
handling cookies, web bugs, and scripting/ActiveX components in addition to
it's firewall functionality. Not free, but I have used it with my other
AdBlocking stuff (AdShield, etc.) turned off as a test, and it appears to be
very good indeed. So far I've experienced no problems at all with it set in
its High Security modes for Ads although others have reported the need to
temporarily turn it off to reach some sites. Also, Agnitum's Outpost
Firewall supports a plug-in for this: "Pre-configured to block most banner
advertisement. Can be configured manually or by simply dragging and dropping
unwanted banners into the Ad Trashcan." I have no experience as to how
effective it is, but I have received a favorable report.

If you install and keep UPDATED a good HOSTS file, it can help you avoid
most adware/malware. See here: <
http://www.mvps.org/winhelp2002/hosts.htm>
(Be sure it's named/renamed HOSTS - all caps, no extension)
You might want to consider installing Eric Howes' IESpyAds, SpywareBlaster
and SpywareGuard here to help prevent getting this kind of adware/malware in
the future:
IESpyads -
https://netfiles.uiuc.edu/ehowes/www/resource.htm "IE-SPYAD adds
a long list of sites and domains associated with known advertisers,
marketers, and crapware pushers to the Restricted sites zone of Internet
Explorer. Once you merge this list of sites and domains into the Registry,
the web sites for these companies will not be able to use cookies, ActiveX
controls, Java applets, or scripting to compromise your privacy or your PC
while you surf the Net. Nor will they be able to use your browser to push
unwanted pop-ups, cookies, or auto-installing programs on your PC." Read
carefully.
http://www.javacoolsoftware.com/spywareblaster.html (Prevents malware Active
X installs) (BTW, SpyWareBlaster is not memory resident ... no CPU or memory
load - but keep it UPDATED) The latest version as of this writing will
prevent installation or prevent the malware from running if it is already

parasites.
