Hi everyone
Just a few last changes while I'm waiting for some last bug reports:
- All listview controls on the configuration dialog are now sized using place-
holder controls on the dialog; this should prevent placement problems on
some systems where the dialog is resized before it's fully initialized (eg:
by some visual aid programs, etc).
- The custom/server listviews now have their "category" column automatically
sized to fit all categories into the list with the system's selected font,
and the "keyword" column is now stretched so the columns fill the list
completely (and when the window is resized also).
- Changed from HeapAlloc to GlobalAlloc to prevent crash when closing certain
programs (eg: the game Deus X) - it seems that these programs have some kind
of automatic heap deallocation system, whatever happens by the time Ad Muncher
tries to deallocate it's buffers the pointers are no longer valid, GlobalAlloc
at least doesn't crash with invalid handles
- Clicking the "about" option in the right-click status bar icon menu now
works correctly even when the configuration window is already open.

I've also made some changes to this beta in regards to sites which
attempt to block people using Ad Muncher - so if anyone using beta 20
finds a site which still blocks their access for using an advert
blocker, please let me know.
Also, for those of you who are handy with IRC, feel free to stop by
EFNet (http://www.efnet.org/ircdb/servers.php) #AdMuncher - this
channel will become one of the official support avenues once v4.4 is
available and it would be nice to see some people hanging about in
there before it's in advertised to the public

Beta 20 can be downloaded from:
http://www.admuncher.com/AM-Beta20.exe

Also, one last request; I've made a lot of minor polishing touches to
the way the custom filter list dialog is displayed and would like to
check they're all working properly across other peoples systems; if you
know how to take a screenshot (jpeg preferred) then I would very much
appreciate a shot of the Ad Muncher configuration window with the custom
lists displayed (and, preferably, with a filter entry being modified at
the time, ie: with the listbox grayed out and the keyword/category
modification boxes visible). Just to check things are lining up the
way I had intended.
Again my sincere thanks for everyone's help in developing v4.4

Yours thankfully,
Murray Hurps

Hi everyone

A few more little changes:
- Web bug removal code now only removes web bugs which are retrieved from a
different host than the page is being served from; this condition is
reliably present in most real web bugs and this should prevent it from
interfering with some simple spacing images.
- Modified background sound removal to removal all <bgsound tags regardless
of whether wav/midi filename was found or not (still checks for filenames
on <embed tags though).
- Modified filtering engine's referer-change code so it doesn't take effect
on any yahoo.com pages (as these pages often don't load properly when the
referer is changed).
- Fixed interpretation of http replies so no space characters are assumed
after each header field; fixes misinterpretation of content length on a
few sites (eg: oracle.com).
- Fixed bug in in-line popup removal, in-line removal would not work at all in
beta 20, heh, I goofed up a pointer and it was giving up after a single
character check.
- The http request interpretation code now doesn't rely on double-byte crlfs
(interpretting single 0x0a's properly) - fixing stalls in certain clients,
eg: yahoo chat's java applets.

Beta 21 can be found at:

http://www.admuncher.com/AM-Beta21.exe

As always my sincere thanks to everyone for their continued testing;
if beta 21 introduces any new problems of course please let me know,
otherwise I'll be releasing it as the official v4.4 at the end of the
month. Ooh, how exciting

Yours sincerely,
Murray Hurps

Hi everyone

Good and very exciting news; I've not gotten any bug reports in the
last week for Beta 22 (except for Marc :-p), a few last minor changes
and v4.4 was put up on admuncher.com, along with a shiny new web page
and the associated files for automatic updates to v4.3d.
I'd like to offer my sincere thanks to everyone for their help in
bringing v4.4 to where it is today, if it weren't for everyone on the
beta list it really would be stuck back at the level v4.3d is at.
If anyone is still absent from the changelog beta credits but wants
to be included please let me know and I'll update the list on
admuncher.com
If anyone (god forbid) finds any further bugs they'll be fodder for
the v4.4a release, but please do let me know about them as usual.
Feel free to tell your friends about the final release of v4.4
and again, my sincere thanks.

Yours thankfully,
Murray Hurps

Hi Everyone

Ah, here we go again. Enclosed are the details of the new Ad Muncher
v4.41 betas - you’re receiving this email because you’ve either tested
previous versions or expressed interest in testing betas - if you
would like to be removed from the beta list please let me know.

Things to look out for in this beta:
- Any popups getting through the new popup removal system
- *Any* page damage, eg: text missing, or pages not loading at all.
- Missed adverts as always
- Any comments on the new sections of the interface (eg: contact,
taskbar options, the "Recently triggered Ad Muncher filters" list,
etc) would also be greatly appreciated.
My sincere thanks for trying the beta versions, we’ve been doing far
more extensive alpha testing on this version so I’m not expecting too
many problems, but of course please do report anything odd that you
encounter
Ad Muncher v4.41 Build 632 *BETA* (note the new version system is
available from:

http://www.admuncher.com/B-4.41.632.exe

Thanks again for your help, please feel free to contact me with any
comments you have on the new version

Yours sincerely,
Murray Hurps

Ad Muncher v4.41 changelog:
===FEATURES===
- Version numbers for Ad Muncher now include build numbers too, ala "v4.41.200"
for build number 200. Build numbers will be started at zero from the start
of v4.41 development.
- New popup removal technique for removing popups which open when a page is
first opened (as opposed to unload/timer ones) - using an embedded javascript
"helper script" - this should prevent a lot of the problems with pages not
loading when their popup functions were integrated with document writing
functions in certain ways (as seen on espn.com), it also allows the neat new
option to "Display popup removal notice in status bar" so you can tell when a
popup has been blocked.
- The above "helper script" was extended to include a javascript error handler
to handle things when certain adverts are removed - finally stops all those
darn "Done, but with errors." messages Internet Explorer was generating, the
handler can be enabled/disabled via the "Suppress Internet Explorer script
debugging" option.
- Added new list to the "Recent items" section named "Triggered Ad Muncher filters"
allowing people to see what Ad Muncher is triggering on, including custom/server
filter entries, advanced filters, as well as all the checkbox options.
Clicking the "Find" button takes you to the section in Ad Muncher’s configuration
where the triggered option/filter can be modified.
- Removed the check that prevented filtering of locally-targeted connections,
it seems far more people than I had thought both use locally installed http
proxies, and don’t know how to configure their filter targets list
- Ad Muncher now doesn’t use OpenProcess and Read/WriteProcessMemory calls for
IPC on winsock hooks - due to the small amount of data transferred (a sockaddr
here, a port and PID there) I switched to simple multiple SendMessage dword
transfers, thus allowing patches of NT services (where otherwise it would
require messy modifications of access rights on the process). WinProxy
filtering here we come
- In addition to the above, created a new "helper DLL" to allow Ad Muncher to
patch into programs running as NT services, and also programs which display
no windows (which would otherwise cause admunch.dll to not load from
SetWindowsHookEx) - testing revealed WinProxy (and I’m sure many other
proxies) are now being filtered correctly. *general applause*
Info on the new helper DLL can be found in the Ad Muncher help file, under
"Helper DLL".
- Trying to launch Ad Muncher when it’s already running now just displays the
configuration window, instead of the notice that it’s already running
(useful when using the icon hiding options).
- Added "+waol:*" to the default filter targets list - Ad Muncher now works
with AOL, hooray!
- Added new section to the "options" tab of the config window to set "Taskbar"
options, new features include:
- Keyboard shortcuts to the config window, and the activate filtering/ip
scramble options.
- Option to "lock" Ad Muncher, added due to several requests.
- Option to hide Ad Muncher icon under certain conditions, eg: when no
programs are connected through it, or when the config window is closed;
also added buttons on the config window to shutdown and lock Ad Muncher
(if a lock password is defined) - so people can still access these options
when the taskbar icon is hidden.
- Added option to Options/Filtering tab to "Remove window move and resize
commands".
- Added option to installer to "Install for all users of this computer" - which
basically just modifies the addition of "start menu/programs" entries and the
automatic launch on startup key.
- Extended handling of "Exclude filtering on site" filter entries so that they
are checked before matching against "remove tables with text" and "remove
scripts with text" entries, essentially so you can override any other filter
entries.
- The "Remove self-focus commands" option now doesn’t affect focus() commands
which reference forms.
- The "Recent programs with outbound connections" list is now updated in real-
time (ie: no need to reopen the config window to refresh).
- The default filter targets list now doesn’t include the "-nav, -outlook" etc
"problem-program" entries. Far too many people were wiping these entries out
(accidentally or otherwise) then emailing me to complain those programs didn’t
work anymore A separate list is now hard-coded into the executable instead.
- Ad Muncher now automatically recreates the taskbar icon after explorer.exe
crashes.
- Config window position is now remembered after the window is closed - the size
is not (for the time being) until I can implement a window resize handler that
doesn’t look so weird when resized
- AdMunch.dll now doesn’t hard-import from wsock32.dll - this was loading some
third party wsock32.dll files when it was passed into SetWindowsHookEx (and hence
loaded in the address space and home directory of each running process) - it
now loads the one from the system directory at runtime.
- Added new filter category, "Prevent page retrieval" to stop specific sites, images
and scripts from loading - nice final resort if you can’t get a script/image removed
via src keyword entries (eg: if the src= tag is obfuscated), or if you want to stop
users from visiting certain sites. Can also be used to prevent favicon.ico retrieval
(ie: the icons Internet Explorer uses for favorites) and lots of other things
- Finally discovered why Internet Explorer would crash when Ad Muncher and Panda Antivirus
are installed together - it seems Panda’s patching system can’t cope with transposing
relative jump instructions (0xe9), Ad Muncher *can* handle them just fine though, so Ad
Muncher now loads wsock32.dll before loading it’s own patches (it used to target only
ws2_32.dll if it was present), panda installs it’s patches when wsock32.dll is loaded so
this allows Ad Muncher to install it’s patches in over the top of pandas, and allows IE
works properly again
- Changed the "Recent programs with outbound connections" list into a "Recent program names"
list - some people were getting confused when programs weren’t listed in the previous list
if they were excluded from filtering (thereby preventing Ad Muncher from patching into
them and noticing when they had outbound connections).
- Changed default timeout value for the IP Scramble scanner from 15 to 4 seconds - 15
really was excessive, and any proxy that takes longer than four seconds to connect and
download a small HTTP reply is really going to slow down browsing anyway
- Switched to 16x16 icons for the taskbar to improve definition, also added new icons to
indicate when IP Scramble is enabled (the cow now wears sunglasses, hehe, undercover,
geddit? ahhh).
- Removed the option to "Blackout Ad Muncher icon" - I’ve had a lot of people question why
it was necessary; if anyone really has a problem with the cow icon please feel free to
contact me with suggestions on a replacement.
- During beta testing the "Blackout Ad Muncher icon" was added again, lol, it seems far
more people than I’d thought were using it - why does everyone hate my cow icon?!?
Also added a version of it with gray sunglasses to indicate when IP Scramble is enabled.
- Popups generated through "<form target=new" type systems can now be removed by using
"Remove popups from site" filters against the URL in the "action=" parameter.
- Web bug removal now checks the image src against any exclude list entries you have, if
a match is found of course the normal web bug removal is not performed.
- Improvements to the code which decides whether a detected "web bug" is from a different
domain - now only tries to check the top level domain name, so if a page on x1.site.com
has a 1x1 image from x2.site.com it won’t be removed.
- Timer-based popup removal now also removes popups generated via SetInterval commands
(not just setTimeout ones).
- Pass-thru GIF/JPEG replacement now doesn’t insert [ad-munched] gifs into the stream,
instead a blank image is now used, simply to avoid the weird looking images when the
image is resized.
- Ad Muncher now includes it’s own miniature IRC client to chat to other users - hopefully
to reduce the number of trivial tech support enquiries and help people get quicker
responses. AM-Install.exe file size went up by 3kb for the full inclusion of the new
client so I’m sure that’s some kind of record for the smallest functional IRC client yet

- The automatic update system now relies on build numbers for both the Ad Muncher
updates and the server-supplied lists updates - should provide more accurate
stats about when Ad Muncher is updated, and save some bandwidth too.
- Automatic updates are now only tried once each month - but the new check doesn’t
rely on Ad Muncher being loaded on certain days of the month (as the previous
v4.4 did, where it would need the day of the month to be a multiple of 8).
- Added confirmation message when the user disables the server-supplied filter list, a
lot of people were turning it off by accident then complaining that Ad Muncher wasn’t
removing adverts
===BUGS===
- Fixed bug where some small HTTP requests were passed through without filtering.
- Lots of little fixes to the nullify routine.
- Fixed admunch.exe hang (100% cpu usage) when filtering certain e-eye pages.
- The v4.3d configuration import code now doesn’t overwrite any settings
already present in the v4.4 config file.
- Popup removal now properly interprets html tags within document.write and
writeln tags within scripts; it would previously identify the code as
javascript commands, occasionally leading to content damage.
- Tag removal code now properly interprets comment tags nested within other tags.
- Proper handling of improperly terminated <iframe tags (ie: without a </iframe>
following).
- Fixed problem with taskbar icon not appearing properly on startup (usually
under windows XP) - removed the "Delay loading by X" option because it’s no
longer necessary
- Nullify routine now does not add a semicolon when removing functions which
didn’t have a semicolon to begin with, fixes problems with certain types of
javascript conditional structures.
- Fixed crash when attempting to save extremely large IP Scramble verified lists.
- Nullify routine now correctly removes badfunction from
"if(condition)badfunction();" (no spaces) without wiping out the if structure
too.
- URL reconstruction now handles URLs without a protocol spec properly, eg:
//site.com/page.htm
- Fixed bug where refresh URL in meta tags would be incorrectly interpreted if
the tag was inside of a script; usually leading to the tag being removed when it
shouldn’t.
- ParseRadix now stops filtering at any non-hexadecimal digits - stops
misinterpretation of content-length fields where the numbers are followed by
spaces.
- SetTimeout("badpopupfunction();", 100) popup generation systems are now removed
properly.
- Popup removal now doesn’t treat document.open() as a popup.
- alert() removal now a lot more pedantic about checking the format of alerts before
removing - fixes some content damage.
- The script and table removal code now checks for a full <script/<table tag,
rather than the previous abbreviated <scr/<tab check.
- Document.referer javascript removal now correctly removes window.document.referer.
- If you remove an advanced filter, then create another, the new filter now doesn’t
appear with the match/replacement texts of the previously deleted filter.
- Fixed 3dsmax crashes.
