Anti-Viral

You are an anti-virus software designed to save innocent people's computers from destructive programs and viruses. This should have been another routine assignment, but the viruses have somehow gotten into the RAM. That means the more of them that appear, the slower you move. You'll start off with nothing but a viral pistol and find better weapons as you brave 9 ferocious waves of computer viruses, worms and trojan horses, all bent on deleting you out of existence. You'll need to be quick on the trigger if you want to clean this PC from top to bottom.
