Quote:
Description
There is a cross-domain scripting vulnerability in the way ITS protocol handlers determine the security domain of an HTML component stored in a Compiled HTML Help (CHM) file. The HTML Help system "...uses the underlying components of Microsoft Internet Explorer to display help content. It supports HTML, ActiveX, Java, [and] scripting languages (JScript, and Microsoft Visual Basic Scripting Edition)." CHM files use the InfoTech Storage (ITS) format to store components such as HTML files, graphic files, and ActiveX objects. IE provides several protocol handlers that can access ITS files and individual CHM components: its:, ms-its:, ms-itss:, and mk:@MSITStore:. IE also has the ability to access parts of MIME Encapsulation of Aggregate HTML Documents (MHTML) using the mhtml: protocol handler.

http://www.us-cert.gov/cas/techalerts/TA04-099A.html

The fix requires brutal sugery of Windows Local Machine Zone resulting in the Help system not working.

Install a HOSTS file that stops the(se) site(s) that exploit this vunerability.
http://webpages.charter.net/hpguru/hosts/hosts.html

Also install a Custom Entry in SpywareBlaster.
Name=CHM exploit | hard-virgins.com
CLSID={11111111-1111-1111-1111-111111111157}

TeMerc - I don't know what I did, but you're welcome. Wink

CalamityKen - on that page with the custom entiries for SpywareBlaster, does it mean that all those shown there should be added? I wasn't clear on that.

Suzi, they should all be added until the next update of SpywareBlaster.

An easy way to add new entries:

Quote:
With SpywareBlaster closed, create a file in its stored folder called customblocking.txt

It has the format:

[Header]

Creating that text file is a lot easier than adding all those individually! Thanks. Very Happy

What goes here: [Header] - Does something go inside the brackets, or just the word Header like shown there?

Just the [Header] Suzi,
and the list total as a number.
For the example above:
If you have 31 entries 0-30;
e.g.
[Header]
ListNumber=31

Got it Iceblue - thanks! Very Happy

And - when you say "stored folder" do you mean the SpywareBlaster folder in the program files? That's the only folder I see for it. All I see in it is five files with .sss at the end.

Speaking of Search.

TrackerV3 is the best for this and has many built in features and a Windows Explorer like shell.

hello
suzi i did a few singal blocking ones through the spyblaster gui and it created this txt file in the program folder its self not that i could find the exe file your looking for. so just putting it in the program folder should work just fine.
but to up date new ones just open the txt folder and copy paste the new ones in.
