Hello list,
Version 1.02 is available which checks if the download directory
exists(or creates the dir) and doesn't download if the newest update
file already exists.
It is written in Python and don't blame me if it doesn't work.

Version 1.02
Symantec Antivirus 8.x, 9.x, 10.x Coporate Edition XDB Definition Updater
Mar-17-2005
-John Taylor
Modified by Sander Nieuwenhuizen @ Sep-27-2006
Automatically updates XDB virus definitions from Symantec's web site.
The program checks if the download directory exists. Otherwise it will create the directory from AVPATH.
Checks if it already has downloaded the latest version.
If you would like you could modify the variables WEBPAGE, TMPPATH and AVPATH
"""
WEBPAGE="http://securityresponse.symantec.com/avcenter/download/pages/US-SAVCE.html";
TMPPATH=r'/tmp/'
AVPATH=r'/install/packages/sav-9.0/update/'
