Being a computer virus isn't easy! You're working all the time trying to eat away at what seems to be an endless supply of hard drive bytes. As if that wasn't hard enough, now comes along a virus cleaner program (anti-virus) to wipe you out! Your goal? Simple! Kep away from the antivirus program while running through each hard drive sector collecting it's bytes. Next, find the exit and get through. Easy? NOT!

There are a few surprises along the way. There are 30 possible sectors for you to "infect". These sectors are divided into small coloured squares. If you step on a blue square it turns yellow. Stepping on a yellow square turns it red. Stepping on a red square turns it into an empty spot. You can no longer step on an empty spot, but the antivirus program can go anywhere. It is relentless, so keep moving and watch over your shoulder. This is just one of the many dilemmas you can face in an attempt to infect all sectors.
