There has been some discussion on the Sanesecurity users list about
ClamAV signatures matching unintended words.  For example, a signature
that is written to match "acebook . com" (remove the spaces) would also
match "facebook . com".

Is there a way to delimit what can precede a signature?  For example,
allow preceding character matching if the preceding character is NOT an
alpha/numeric character?

This would allow all of the following to match:

http://acebook . com
http://your.acebook . com
http://your.acebook . com/some/path.htm

But not match:

http://facebook . com
http://www.facebook . com
http://www.facebook . com/some/path.htm

Thoughts or suggestions would be greatly appreciated.

Bill
