In this Instructable, I will show you how to swap the mouse buttons on your computer (this can be extremely funny when you send it to a friend). This does nothing harmful to your computer, all it does is makes the left mouse button right click and vice versa!

Step 1: Step 1 - Downloading in Shadow

You need to download In Shadow Batch Virus Generator.
Without this, you won't have a clue what's being typed down!
After you downloaded it, drag In Shadow to your Desktop.

Step 2: Step 2 - Opening in Shadow

This is In Shadow. To swap the mouse buttons, you need to click Options.

Step 3: Step 3 - Adding the Code

Once you've clicked Options, you need to click 'Swap Mouse Buttons' under 'Funny/Misc.'.

Step 4: Step 4

After clicking 'Swap Mouse Buttons', some code will appear under @echo off.

Step 5: Step 5 - Saving the File

Right, now you need to go back to 'Creation Options'. It is optional to type in your name into the little black box in the side and the Virus Name in the box at the bottom.
Now click 'Save as Bat'. Save it as whatever you want, wherever you want.

Step 6: Step 6 - Opening Your Bat

Now look in the folder you saved it in. You can click it and it works! (To be honest I haven't tried clicking it again to try and switch them back!)

Optional:
You could convert it to an exe using 'Bat to Exe Converter'.
