Adware Keeps Coming Back

Guest

I aquired some adware on my system that keeps re-installing whenever I browse
the net. I have removed it every time with spysweeper2. The program is named
CWS_NS3. My Internet Explorer acts strangely now and many of the
advertisement photos don't load. I checked the registry for all of the files
that were listed in the Spysweeper browser. Anybody know about this adware?

Hi MrB :)

There are some variants that can replicate and mutate themselves repeatedly
if not removed properly. Do the following and see if it helps:

Dealing with Unwanted Spyware and Parasites:
http://mvps.org/winhelp2002/unwanted.htm
Be sure to run CWShredder 2.0, Ad-aware and Spybot.
Also be sure to use the HijackThis. Please DO NOT post your log to this
newsgroup, but to the SpywareInfo or the Aumha HiJackThis forums
http://forum.aumha.org/viewforum.php?f=30, to allow the experts there to
evaluate your log and advise you of the necessary steps to clean your
system.

CAUTION!!!!! Before you try to remove spyware using any of the programs
below, download a copy of LSPFIX from any of the following sites:
http://www.cexx.org/lspfix.htm
http://www.spychecker.com/program/winsockxpfix.html
(if your OS is Win2k or XP) The process of removing certain malware may kill
your internet connection. If this should occur, this program, LSPFIX, will
enable you to regain your connection.

Also, get a copy of WINSOCKXPFIX available at:
http://www.spychecker.com/program/winsockxpfix.html
and
WinsockXP Fix- WinXP
http://www.spychecker.com/program/winsockxpfix.html
Also, with instructions, at

(NOTE: It is reported that in XP SP2, the command netsh winsock reset
will fix this problem without the need for these programs.)

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, and then run. This scan may take a long
time, as Sysclean is VERY extensive and thorough

and......

NOTE: If you can not download these programs from the Internet, if your PC
has CD read capabilities, go to another computer with CD-ROM burning
capabilities. Create a folder on the hard drive of the other computer called
HOLD, download the programs to that folder, then burn that folder to a CD.
Copy the HOLD folder to your HD and then install the programs from there
and run them. After you have IE access again, update all programs where
possible to get the latest definitions and run them again in Safe Mode to be
sure there are no lingering items on the system.


If it still comes back, then go to the more indepth methods:

Also courtesy of Jim Byrd -

Like any disinfection procedure, it's a bit risky - it deletes an important
registry key and subsequently restores a revised version. If something goes
wrong, your PC may no longer work normally.

YOU USE THIS PROCEDURE AT YOUR OWN RISK!

Download Registrar Lite 2.0, install it and run it.
http://www.majorgeeks.com/download469.html
http://www.softpedia.com/public/cat/12/5/12-5-21.shtml

Navigate to this key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows
(note...should be all on one line)
and look at the AppInit_Dlls value.

Write down the name of the DLL file that's displayed!

(If you see several values separated by commas or spaces, which is unlikely,
use Windows Explorer to search for each one in the Windows\System32 or
Winnt\System32 directory. The one you can't find is the one to remember!)

Exit Registrar Lite.

Download and run this script. It will delete the CWS AppInit_Dlls value and
reboot Windows. After the reboot, the shield-DLL file is still on the hard
disk, but it's no longer a threat to your PC.
http://www.silentrunners.org/CWS Shield Dropper.vbs

Download Silent Runners here:
http://www.silentrunners.org/Silent Runners.vbs
Run it and look at the list of Browser Helper Objects. One of them will have
a strange name. Write down the the file name (including the full path)!

(If you're not sure which BHO was installed by CWS, reboot into Safe Mode
and follow steps 8-10 here. Commercial programs, such as PestPatrol, are
also available to identify and delete BHO pests.)

Download and run this script to delete the CWS shield-DLL and the BHO files.
No reboot will be required.
http://www.silentrunners.org/CWS File Cleaner.vbs

Reset your Internet Explorer home page. Your PC should now run normally.

If these steps do not resolve your problem, please post back to this thread
with the details and any error messages.

Hope this helps

oops!!

Please be aware that there is some talk about the possibility of SpySweeper reporting (too many) false positives.

I've tested it and found exactly that same problem (funny coincidence..??) and also the "securybanks phishing trojan" common to many users of SpySweeper.
