Your Objective:
The files on the computer have been corrupted by the viruses. A diagram displaying how the originial file looked will be displayed on your left. You must restructure the corrupted file to look like its original image.

How to Play:
In each file you will see colored blocks of code. If there is an empty spot open to the left, right, top or bottom of the code block you can click on it to move it in that direction. Whenever you reposition a block of code into the same position it occupied in the original file you get 100 points (this only works once for each block of code). You are given ten minutes to restore each file. If you cannot do it in ten minutes the game is over. For each minute that is left over when you complete a file you get 200 points. There are also two other types of code blocks: The header and the antivirus code blocks. These will be explained in just a moment.

The Viruses:
The viruses have one main goal... to locate and attack the header code (bright yellow square with a white border). If a virus successfully lands an attack on the header code, the file is rendered unrepairable and the game is over. Whenever a virus begins an attack, a counter will appear above them. When the counter reaches zero several things can happen:

- If there is nothing under the virus nothing happens.
- If the header code is under the virus, the game is over.
- If a regular block of code is under the virus the file is scrambled in a pattern determined by the virus.
- If the antivirus code is under the virus, the virus is destroyed.
Note: The viruses will always attempt to attack the header code and will sometimes attempt an attack on a regular block of code.
Also Note: For each virus you kill you get 100 points.

Upgrades:
At the end of each file you are given the chance to buy upgrades. There are two different ways to get points for the upgrades:
- You get 5 points when you move a block of code into its correct position.
- You get 50 points when you destroy a virus.

There are 4 different upgrade that can be purchased:
- Bug Bomb - If you have one of these you may use it to destroy all the viruses on the screen. Note: You do not get points for viruses destroyed in this way.
- Bug Blocker - If you have one of these you may use it to stop all viruses from entering the file for 20 seconds.
- Anitvirus Code - Buying one of these will add an extra block of antivirus code to the next file (only lasts for one file).
- Decoy Code - Buying one of these will add a decoy code block to the next file. A decoy will trick a virus into attacking it but it contains antivirus code (only lasts for one file).
