The homepage in my IE gets changed automatically when I
reboot. I tried using the free spy software removers, but
it did not fix this problem. Does anyone know where else
I can look?

Since the change seems to happen when you reboot it seems likely that some
program is being run at that time to make the change. Have you tried running
msconfig (start > run > msconfig) to see what is running at startup? I'll be
the first to admit that the flood of information it provides can be
overwhelming to the uninitiated but often the offending program will stand
out clearly.

Hi Chris - It sounds like you've been hijacked. If you go to this page
at Jim Eshelman's site, here: http://aumha.org/a/noads.htm and wait a
little bit (be patient), an analysis of a number of possible parasites
on your machine will be made to help you identify and remove them.
NOTE: You will need to disable Ad Blocking in Zone Alarm 3.x, if
present or any other Ad Blocking software which interferes with Java
Scripting for this scan to work. You should get a message between the
two lines of **** giving the results of the scan.

For the general hijack case, the best way to start is to get Ad-Aware
6.0, Build 162 or later, here:
http://www.lavasoftusa.com/support/download/. Update and run this
regularly to get rid of most "spyware/hijackware" on your machine.

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. After fixing 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.


Note that sometimes you need to make a judgement call about what these
programs report as spyware. See here, for example:
http://www.imilly.com/alexa.htm

Lastly, a very useful utility for examining your system and correcting
problems is Hijack This, which you can download here:
http://www.spywareinfo.com/~merijn/files/hijackthis.zip See also,
HijackThis Quick Start Help, http://www.tomcoyote.org/hjt/ (Recommended)
This site has a number of useful references and information also:
http://www.spywareinfo.com/articles/hijacked/ and here
http://www.spywareinfo.com/downloads.php

Another program giving a good inventory of all of the possible start
vectors is AutostartExplorer, here: http://www.misec.net/aexp.jsp
While it doesn't allow control of startups, it's extremely comprehensive
in examining all of the possible sources. Highly Recommended

Next, go here: http://www.mlin.net/StartupCPL.shtml and get Mike Lin's
Startup Control Panel applet. A somewhat more difficult to use but
more extensive program to do the same thing is StartupList from here:
http://www.lurkhere.com/~nicefiles/index.html, or even better, Autoruns
from here:
http://www.sysinternals.com/ntw2k/source/misc.shtml#autoruns. Be very
careful about doing any Registry modifications directly unless you're
comfortable with this, and be sure that you BACKUP your Registry before
making any changes, so that you can recover if something goes wrong.
Changes made with StartUpCPL are less likely to cause problems, and are
usually a matter of just re-enabling the particular program. Another
program of this type that I can recommend is StartMan, free, here:
http://www.spywareinfo.com/downloads/startman/. If you have problems
with suspected hijackers, you can look up and investigate suspect
programs in your StartUp lists here:
http://www.pacs-portal.co.uk/startup_pages/startup_full.htm
(Recommended)
http://www.3feetunder.com/krick/startup/list.html (Recommended)
http://www.answersthatwork.com/Tasklist_pages/tasklist.htm (Recommended)


Some hijackers install themselves as Browser Helper Objects. Get BHOCop
here: BHO Cop http://www.pcmag.com/article2/0,4149,270,00.asp
(Unfortunately, no longer free from that link but you can read about it
there, and here is a direct download link for it:
http://websec.arcady.fr/bhocop.zip) and take a look at what BHO's are
currently installed. Some things like AdShield and Acrobat are normal,
but if you see something that doesn't make any sense, try disabling it
and see if that helps. Another excellent program for this same purpose
is BHODemon, (still free) here: http://www.definitivesolutions.com/ or
here: http://www.spywareinfo.com/downloads/bhod/ I would recommend
both. You can also check/control BHO's using the Tools function of
SpyBot S&D.

There's good information about hijacking and fixes available here:

Andrew Clover's parasite page: http://www.doxdesk.com/parasite/
(Highly recommended)
Robert Allen's parasite page: http://allentech.net/parasite/index.phtml
(Highly recommended)
http://www.spywareinfo.com/hijacked.html
http://gmpservicesinc.com/Articles/hijack.asp (links here for .reg files
to lock and unlock your homepage, BTW. You can also use this program to
toggle locking/unlocking of your homepage:
http://www.dougknox.com/security/scripts/nosethomepage.vbs Recommended)
http://www.mvps.org/inetexplorer/answers.htm#home_page

Also, there's a new class of hijacker using Window's Messenger Service
(not Instant Messaging, BTW). 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.
These are due to open NetBios ports 135, 137-139 and
445. 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.

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 messaages 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.

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.)

Once you get this cleaned up, you might want to consider installing the
Browser Hijack Blaster, SpywareBlaster and SpywareGuard here to help
prevent this kind of thing from happening in the future:
http://www.wilderssecurity.com/bhblaster.html (Prevents malware BHO's)
http://www.wilderssecurity.com/spywareblaster.html (Prevents malware
Active X installs) (BTW, SpyWare Blaster 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 installed, and it provides information and fixit-links for
a variety of parasites.
http://www.wilderssecurity.net/spywareguard.html (Monitors for attempts
to install malware) All three Very Highly Recommended.

See if any of this helps and post back with your results.

msconfig didn't work for some reason. I have a win2000
machine. How else can I tell what runs at startup?
Thanks for your help by the way.
