# Date: Oct 28, 2010
# Author: chr1x
# Software Link: http://downstairs.dnsalias.net/files/HomeFtpServerInstall.exe
# Description: Home Ftp Server is an easy to use FTP server, that allows you to share files directly from your PC with lots of setup possibilities. You can set up user accounts, specify directory permissions and monitor access to individual files. It supports virtual directories, banned IP addresses and offers a web based administration interface that lets you add users and view current statistics.. and much more.
# Version(s): vr1.10.3 (build 144) AND v r1.11.1 (build 149) <- Yeah, two versions, same payloads! ]¬)
# Tested on: Windows XP SP3 (Spanish Edition)
