There are many people who have helped this FAQ improve over time - MVPs and
newsgroup users. I thank all of you who have made the newsgroups,
anti-malware websites and dedicated mailing lists into such a wonderful
resource.

Read the advice at my prevention link
(http://inetexplorer.mvps.org/data/prevention.htm) to reduce the chances of
your computer being infected.

IMPORTANT: Before trying to remove spyware, download a copy of LSPFIX from
the URL below - some malware can kill your internet connection when it is
removed, and this software should get things going for you again:
http://www.cexx.org/lspfix.htm

Also get a copy of WINSOCKFIX available at:
http://www.spychecker.com/program/winsockxpfix.html

The software you should download and have ready to use is:

AdAware - www.lavasoft.de [..Warning: AdAware is now version 6.181. All
previous versions are NO LONGER SUPPORTED and will not be updated...]

Spybot Search and Destroy - http://spybot.eon.net.au

HijackThis - http://209.133.47.12/~merijn/files/HijackThis.exe

CWShredder - http://www.merijn.org/files/CWShredder.exe

IMPORTANT: After obtaining the required software above, make sure you check
for updates and run the programmes in safe mode.

Malware removal (beginner's guide):

First, go to Control Panel, add/remove programs. Check for malware entries
and use the uninstall programs, then reboot.

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]

[...Information about safe mode...By starting in safe mode, you are
disabling startup programmes and 'non-essential' services. Note that some
hardware, such as USB devices, audio devices and IEEE 1394 devices will not
work properly, or at all, in safe mode. Services that WILL load in safe mode
are listed at the following registry keys:

Safe mode
HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Control \SafeBoot \Minimal

Safe mode with networking
HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Control \SafeBoot \Network
...]

Start CWSHREDDER. Update it, and fix anything it finds. Reboot back into
safe mode.

Start AdAware. Use the 'check for updates now' option. After you have
updated, click 'start'.

Note that when run using default settings, AdAware does not cope with new
'intelligent' malware. Make the following changes to the default settings.

Use the option 'select drives/folders to scan'. Set AdAware to scan your
entire hard drive.

Make sure 'activate in depth scan' is enabled.

Select 'use custom scanning options' and then click on the 'customize'
button. Turn on the following scan options - scan within archives, scan
active processes, scan registry, deep registry scan, scan [my] IE favorites
for banned URLs, and scan [my] hosts file.

Use the 'tweak' button. Turn on the following options:

Cleaning engine: 'automatically try to unregister objects prior to
deletion', 'let windows remove files in use at next reboot', 'delete
quarantined objects after restoring'.

Scanning engine: 'unload recognized processes during scan'.

After you have finished with AdAware run Spybot to pick up any leftovers.
Fix anything marked in red. Again, don't forget to check for updates.

Also do the following:

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
*** chosen (under User Style *** - format documents using my style
***). If the option is turned on, turn it OFF.

If the problem comes back, start all over again but with the following
changes (this section requires advanced computer skills - inexperienced
users will require assistance):

Examine win.ini using MSCONFIG to see what is loading. You may find
something there. Go to MSCONFIG and go to the General tab. Turn off
process win.ini file, load system services and load startup items. Restart
Windows and run AdAware etc once more.

Use services.msc to see what is running. Some malware is now registering
itself as a Service. The problem is working out what is legitimate and what
is not.

I strongly recommend that unless you have strong experience working in this
area that until such time as I am able to track down a comprehensive list of
legitimate services (or put one together myself), that you post details of
the services revealed by services.msc to a microsoft.public newsgroup for
professional guidance. If you turn off the wrong service you could cause
serious problems, and at the very worst, leave the computer unbootable.

An experienced computer technician can use programme such as AutoStart
Viewer for in-depth diagnosis:
http://www.diamondcs.com.au/index.php?page=asviewer

Another excellent programme for the experienced user is APM (Advanced
Process Manipulation), available at:
http://www.diamondcs.com.au/index.php?page=apm

Once the computer is clean, and if it applies to the operating system,
create a new restore point. The old ones may, of course, be infected with
the malware and therefore cannot be used. Run disk cleanup to remove old
restore points (if your operating system has this option you will find it on
the 'more options' tab of the disk cleanup utility. If the option to remove
old restore points is not available, stop and restart the restore service
which will flush out old restore points and prevent accidental reloading of
malware.

MS have released a limited KB article regarding what they call 'deceptive
software'.
