Are you tired of hackers having their way with your computer? Now VirusMD Personal Firewall gives you the power to fight back! This handy utility will monitor up to 12 user selectable ports at a time, including 'negative ports' that most modern firewalls miss, and it will sound an alarm klaxon when an intruder is detected. What makes this program truly unique is that it will also send a message of your choice back to the hacker. There are currently 250,000 copies in use worldwide.
