Antivirus is a game for the iPhone/iPod Touch where you defend your System from attacking computer Viruses. A Tower Defense Genre game, but this time the Virus' fight back. Spam comes in ceaseless waves, Malware disables your defenses, Denial of Service crushes them, Trojans steamroll over you ... just like real life! You have to balance how much power you spend, because that's also your life. Tricky that.
