Before trying to remove spyware:
Back up all essential data.
Download the recommended software listed below.
After all software has been downloaded, installed and updated disconnect the
computer from the internet and/or any network to which it may be attached.
The software you should download and have ready to use is:
Lspfix and Winsockfix, available at
http://www.cexx.org/lspfix.htm and
http://www.spychecker.com/program/winsockxpfix.html
A BHO disabler such as BHO Cop, BHO Demon or BHOCaptor (non XP SP2 users
only)

http://www.definitivesolutions.com/bhodemon.htm
http://www.webattack.com/get/bho.shtml
AdAware (note that Lavasoft have now released Ad-Aware SE Personal Edition,
available from
http://www.lavasoftusa.com/support/download/ AdAware 6 users
should update to SE as soon as possible. All previous versions are NO LONGER
SUPPORTED)

Extract the BAT file to your desktop.
After obtaining the required software above, make sure you check for updates
and run the programmes in safe mode.
Malware removal (beginner's guide):
Go to Control Panel, Folder Options, View Tab. Turn on the option to show
hidden files. Turn off the option to hide protected system files.
***WARNING!! Files are hidden by Windows for a very good reason. It is not
wise to 'experiment' with these files. Unfortunately, to successfully remove
modern malware we must turn this protection off. There is a risk to doing
this. Please turn the protection back on when you have finished cleaning
your system.***
Run HackerDefender Disabler. A DOS window will flash onto your screen and
then disappear. This is normal.
If you are using Windows XP SP2 download and install Update KB888240 to
solve a known problem where add-ins will sometimes hide themselves from the
Add-On Manager. The hotfix is available from:
http://www.microsoft.com/downloads/...9e-b116-4d38-b00c-ff1d529106c8&displaylang=en
Go to Control Panel, add/remove programs. Check for malware entries and use
the uninstall programs, then reboot. Check all 'startup' folders at
...\Documents and Settings\All Users\Start Menu\Programs\Startup or
...\Documents and Settings\<username>\Start Menu\Startup
Go to start/run and type MSCONFIG. Go to the startup tab. Disable everything
that you do not recognise as legitimate (do not disable any power profile
options).
Now go to the Services tab. Turn on the option to 'hide all Microsoft
Services'. Disable everything that remains. If you don't have this option,
don't worry about it.
Reboot your computer and hold down the F8 key until the boot menu options
appear. Choose Safe Mode as your startup choice. You will find information
about what safe mode is, and what it does, at this link
[
http://inetexplorer.mvps.org/data/safe_mode.htm]
If you are using Windows XP, go to Tools, Manage Add-Ons and disable
anything you don't want or recognise. If you are not running XP SP2 use one
of the BHO disablers mentioned earlier.
Empty your IE cache and your other temporary file folders, eg: c:\temp,
c:\windows\temp or C:\Documents and Settings\<name>\Local Settings\Temp (the
path to your temp folder will change depending on your name) - sometimes
programmes can be hidden in there - watch out for mysterious *.exe files or
*.dll files in those folders.
Go to IE Tools, Internet Options, Temporary Internet Files {Settings
Button}, View Objects, Downloaded Program Files. Check for unrecognised
objects there.
Go to IE Tools, Internet Options, Accessibility. Make sure there is no style
sheet chosen (under User Style Sheet - format documents using my style
sheet). If the option is turned on, turn it OFF.
Start CWSHREDDER and fix anything it finds. Reboot back into safe mode.
Start AdAware.
Remember to update using the 'check for updates now' button. Update, then
select 'start' option.
Make sure that 'search for negligible risk entries' is turned on. Select
'use custom scanning options' then select 'customise'. Make sure the
following options are enabled: 'scan within archives', 'scan active
processes', 'scan registry', 'deep scan registry', 'scan my IE favorites for
banned URLs', 'scan my Hosts file'.
Select the 'tweak' option. Under 'scanning engine', make sure 'unload
recognized processes and modules during scan' is enabled. Enable 'scan
registry for all users instead of current users'.
Under 'cleaning engine' turn on 'always try to unload modules..', 'during
removal unload explorer and IE if necessary', 'let windows remove files in
use at next reboot', 'delete quarantined items after restoring'.
Use the 'select drives and folders to scan' option to ensure that your
ENTIRE hard drive is scanned (if you have more than one hard drive, scan all
of them (of course, do not include floppy and CD/DVD).
Once finished, reboot again into safe mode. Run Spybot S&D. "Fix" anything
marked red.
If you are unable to get on to the internet after cleaning up your computer,
run LSPfix. If that doesn't work, run Winsockfix.
If you are using XP SP2 and are unable to access the internet after removing
malware, the following commandline may help - it will reset the winsock
catalogue:
netsh winsock reset
If the malware problem comes back further specialised assistance is
available via the Hijackthis forum at
http://forum.aumha.org - make sure you
read the top announcements about pre-post steps you should take before
generating a hijackthis log.
