AntiVirus is a fast-paced pixel-art tower defense game in which you deploy your Antiviruses to stop the waves of invading computer viruses from reaching your CPU.
Place a variety of Antiviruses along the path of the invading viruses in order to defend your CPU, earn more credits, and up build more defenses to fight off the ever quickening waves of enemies. Take the fight across a variety of levels in a campaign series, or make your last stand and see how long you can last in the endless modes.
With 4 different worlds, each containing 5 different levels and an endless mode, you can either jump in for a quick defense session or grind out a new highscore.
