A computer has received a nasty virus! As the Antivirus, you must defend the computer at all costs! Move with the arrow keys, and aim and shoot with the mouse. Shoot the red circles before they get to the yellow one, but don't shoot the small yellow circles! If they get the CPU, they give you a random buff for a short time! Even you shouldn't touch the red circles either. Survive as long as you can, and have fun!
