Hello all

Thank you very much for reading along.

My computer is installed with a Windows 2000. When I check the
processes my computer is running using Task Manager, I found a process
named:
slsxdq.exe

I further found that it is located at C:\WINNT\system32\

When examining the registry of
My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run,
I found the following information:
Value name: jmjbldpz
Value data: C:\WINNT\system32\slsxdq.exe

It appears that this is at least a trojan, so I deleted the registry
item and move the slsxdq.exe file to another location.

When I restarted my computer, a weird thing takes place:
the same registry re-appears in
My Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
except that the Value name change to some random combination of letter
that I did not take down. The value data is still
C:\WINNT\system32\slsxdq.exe.
Of course, since I moved the slsxdq.exe to another location. The
process is not running.

But how could I stop this registry item being automatically added ?
Presumably there is a virus/trojan is doing this.

Thank you vey much for the help.

Alex

There are all kinds of virus and malware that behave in this
maner. Use your antivirus software to find the culprit. Some
spyware programs can also behave in this maner so do a spyware
scan on your machine. You can do an online virus scan here:

http://security.norton.com/sscv6/default.asp?langid=ie&venid=sym

For spyware scan/removal try AdAware or Spybot Search & Destroy.

All good. I'd add CWSShredder perhaps.
http://www.intermute.com/spysubtract/cwshredder_download.html
 
Hi Alex - Sounds like this might be a variant of some malware called
CoolWebSearch (if CWShredder doesn't fix it, then see AdAware, SpyBot, and
HijackThis, below, in that order). Read all of this carefully first, then do
the following in order:


#########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.

#########IMPORTANT#########



#########IMPORTANT#########
Show hidden files and run all of the following removal tools from Safe mode
or a "Clean Boot" when possible. 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: 1. Start|Run enter msconfig.
2. In the Startup tab, click the "Disable All" button.
3. In the Services tab, check the "Hide All Microsoft Services" checkbox,
and then click the "Disable All" button.
4. Click OK and then reboot.
#########IMPORTANT#########


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:
http://download.nai.com/products/mcafee-avert/stinger.exe or from the link
on this page: http://vil.nai.com/vil/stinger/ ME/XP users be sure to read:
http://vil.nai.com/vil/SystemHelpDocs/DisableSysRestore.htm


Download sysclean.com , from Trend Micro, here:
http://www.trendmicro.com/download/dcs.asp along with the latest 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/). (If you download and use the updater from
the beginning, it will automatically handle downloading the other files.)
Place them in a dedicated folder after appropriate unzipping. Show hidden
and system files (HowTo here:
http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2002092715262339)
Disable Restore if you're on XP or ME (directions here:
http://vil.nai.com/vil/SystemHelpDocs/DisableSysRestore.htm), then boot to
Safe mode (HowTo here:
http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001052409420406)
Read tscreadme.txt carefully, then do a complete scan of your system
in Safe mode and clean or delete anything it finds. 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.



Download, UPDATE before running, and run:
http://www.intermute.com/spysubtract/cwshredder_download.html (The new v.2
which will automatically install in C:\Program
Files\InterMute\SpySubtract\CWShredder.exe and put a shortcut on the
Desktop. Run the program from this install location or the shortcut after
installation. This recommendation for CWShredder is NOT automatically a
recommendation for the other programs adverstised by Intermute in
conjunction with this install.) or
http://209.133.47.200/~merijn/files/CWShredder.exe or here:
http://hem.bredband.net/b157129/f/cwshredder.zip or here:
http://www.softpedia.com/public/scripts/downloadhero/10-17-150/ or here:
http://www.zerosrealm.com/downloads/CWShredder.zip
to remove the parasite. Try to run from Safe mode or a Clean Boot and be
sure to close ALL other programs to the extent possible, expecially ALL
instances of IE and OE.


There's a good tutorial about CWS and using CWShredder here:
http://www.bleepingcomputer.com/forums/index.php?showtutorial=47#domain See
also: http://cwshredder.net/cwshredder/cwschronicles.html

BE SURE that you get v.1.59.0.1 or later or the new v.2! Note that
CWShredder may make deletions/changes to your HOSTS file (sometimes as false
positives), and that after cleanup you may need to restore it with a fresh
copy of any local DNS and/or blocking entries or disable it before running
CWShredder.


You will need to show Hidden files first and then at the end clear the
malware garbage from your System Restore backups after you've cleaned up.
It's best to perform CWShredder (and most other malware fixers too) from
Safe mode and then reboot. AFTER cleaning things up, then you can disable
and then re-enable System Restore. See ******** below.

The following links give instructions on how to do these various functions:


HOW TO Restart in Safe Mode
http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001052409420406

HOW TO Enable Hidden Files
http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2002092715262339

HOW TO Disable/Flush System Restore (do this at the end AFTER cleaning or
use the suggested procedure for XP at the ******'s)
http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001111912274039
(WinXP)
http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001012513122239
(WinME)
or http://vil.nai.com/vil/SystemHelpDocs/DisableSysRestore.htm (Both)



Then download and run:
http://www.kellys-korner-xp.com/regs_edits/iegentabs.reg to restore your
tabs and remove any restrictions that the parasite has put in place.

Now download and run:
http://www.kellys-korner-xp.com/regs_edits/RestoreSearch2.REG to restore
your search functions if they've been affected (as they probably will have
been).


Be sure that you also download and install hotfix Q816093, here:

http://support.microsoft.com/?kbid=816093

which blocks the exploit upon which this parasite family depends.


Another program which performs a similar function to CWShredder is
xcleaner_free (there's a more extensive paid version also) available here
which should also be freshly downloaded and run after you run CWShredder:
http://www.xblock.com/download-freeware.shtml


However, this also indicates that you may have acquired some other malware
along the way. 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 or later, 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.

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 or the
directions immediately below 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.....

<Begin Setup Directions>
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?"
<End Setup Directions>

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". Then 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. After UPDATING and 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.

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

Both of these programs should normally be UPDATED and run after doing any
other fix such as CWShredder and, as a minimum, normally at least once a
week.


When done, go to Start|Run and enter one line at a time (or much easier,
open a DOS box and copy the following in its entirety and then paste it into
the box):

regsvr32 /i browseui.dll
regsvr32 /i shdocvw.dll
regsvr32 /i mshtml.dll
regsvr32 mshtmled.dll
regsvr32 actxprxy.dll
regsvr32 /i urlmon.dll
regsvr32 scrrun.dll
regsvr32 comcat.dll
regsvr32 Oleaut32.dll
regsvr32 /i Shell32.dll
regsvr32 Msoeacct.dll
regsvr32 "C:\Program Files\Outlook Express\Msoe.dll"
regsvr32 msjava.dll
regsvr32 jscript.dll
regsvr32 Olepro32.dll
regsvr32 Hlink.dll
regsvr32 Asctrls.ocx
regsvr32 Inetcpl.cpl /i
regsvr32 Dxtrans.dll
regsvr32 Dxtmsft.dll
regsvr32 Imgutil.dll
regsvr32 Msxml.dll
regsvr32 Msjava.dll
regsvr32 Jscript.dll
regsvr32 Softpub.dll
regsvr32 Wintrust.dll
regsvr32 Initpki.dll
regsvr32 Dssenh.dll
regsvr32 Rsaenh.dll
regsvr32 Gpkcsp.dll
regsvr32 Slbcsp.dll
regsvr32 Cryptdlg.dll
regsvr32 Msjet40.dll
regsvr32 pdm32.dll
regsvr32 Msjtor40.dll
regsvr32 Dao360.dll
regsvr32 Sccbase.dll


with a Return after each .dll. You'll get a message about successful
completion of the re-registration process after each one, then enter the
next (with the DOS box they'll be continuous except for the last one).

If you use Win98x and get an error on Shell32.dll, ignore it. Only the ME,
Win2k and XP versions of windows have shell32 as an object that needs
registering. (For these earlier operating systems, run "regsvr32
shdoc401.dll " instead of "regsvr32 Shell32.dll".) Depending on your
system, you may also get "not found" error messages on some or all of the
last five - if so, ignore them.

Re-start your computer when you've finished.



If they don't fix it then start here:

Download HijackThis, free, here:
http://209.133.47.200/~merijn/files/HijackThis.exe (Always download a new
fresh copy of HijackThis [and CWShredder also] - It's UPDATED frequently.)
You may also get it here if that link is blocked:
http://www.majorgeeks.com/downloadget.php?id=3155&file=3&evp=3304750663b552982a8baee6434cfc13
or here: http://www.bleepingcomputer.com/files/spyware/hijackthis.zip

There's a good "How-to-Use" tutorial here:
http://computercops.biz/HijackThis.html

In Windows Explorer, click on Tools|Folder Options|View and check "Show
hidden files and folders" and uncheck "Hide protected operating system
files". (You may want to restore these when you're all finished with
HijackThis.)

Place HijackThis.exe or unzip HijackThis.zip into its own dedicated folder
at the root level such as C:\HijackThis (NOT in a Temp folder or on your
Desktop), reboot to Safe mode, start HT (have ONLY HT running - IE MUST be
closed) then press Scan. Click on SaveLog when it's finished which will
create hijackthis.log. Now click the Config button, then Misc Tools and
click on Generate StartupList.log which will create Startuplist.txt

Then go to one of the following forums:

Register if necessary, then sign in and READ THE DIRECTIONS at the beginning
of the particular site's HiJackThis forum, then copy and paste both files
into a message asking for assistance, Someone will answer with detailed
instructions for the removal of your parasite(s). Be sure you include at
the beginning of your post a description of "What specific
problem(s)/symptoms you're trying to solve" and "What steps you've already
taken."


*******
ONLY IF you've successfully eliminated the malware, you can now make a new,
clean Restore Point and delete any previously saved (possibly infected)
ones. The following suggested approach is courtesy of Gary Woodruff: For XP
you can run a Disk Cleanup cycle and then look in the More Options tab. The
System Restore option removes all but the latest Restore Point. If there
hasn't been one made since the system was cleaned you should manually create
one before dumping the old possibly infected ones.
*******


Once you get this cleaned up, you might want to consider installing Eric
Howes' IE-SpyAds, SpywareBlaster and SpywareGuard here to help prevent this
kind of thing from happening 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
installed, and it provides information and fixit-links for a variety of
parasites.

http://www.javacoolsoftware.com/spywareguard.html (Monitors for attempts to
install malware) Keep it UPDATED. All three Very Highly Recommended

SpywareBlaster is probably the best preventive tool currently available,
expecially if supplemented by using the Immunize function in SpyBot S&D and
a good HOSTS file (see next). IMPORTANT NOTE: A good additional source of
preventive blocking for ActiveX components is the Blocking List available
here: http://www.spywareguide.com/blockfile.php While smaller than the
SpywareBlaster list, it contains some different malware CLSIDs and appears
to be updated with new threats more frequently. Recommended as a supplement
to SpywareBlaster. Read all of the instructions in the Expert package
download carefully. You might want to consider using:
http://www.changedetection.com/monitor.html to monitor and notify you of
changes/updates to this (or others, for that matter) list.


Next, 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) Additional
tutorials here:

(overview)


Finally, be sure that you have a good hardware or software firewall and an
AntiVirus installed, and bring your OS up-to-date with ALL Critical updates
from Windows Update.

Is there a way (not by software) of finding the hiden process that add
the registry item upon re-start of my computer. What I know is to
check registry and processes. What other places should I check ?

Thanks
 
Look for them here. If you don't get them all in one shot then any one of
them may be capable of spawning the others back into action. Once identified
then while logged off and deleting them remotely from file system and use of
remote regedit is helpful. Natively you can; Start\Settings\Control
Panel\Administrative Tools\Computer Management(Local)\System
Information\Software Environment\Startup Programs|View|Advanced, then in the
"Location" column, you'll find the path to the "Startup" location either in
the "Startup" directories or from the registry's "Run" keys. (note that this
windows is read-only so you must manually navigate to the location below to
edit or otherwise delete)

%ALLUSERSPROFILE%\Start Menu\Programs\Startup
%USERPROFILE%\Start Menu\Programs\Startup

You can delete the shortcuts that you no longer want to run.


HKLM\Software\Microsoft\Windows\CurrentVersion\Run
HKCU\Software\Microsoft\Windows\CurrentVersion\Run

You can delete the string value for the program you no longer want to run.
