1. Get a New e-mail Address your friend doesn't know about the send an email to them that makes them think that you sent them a virus Just dont put in any virus codes
2. Find a fake virus that pretends to delete files or shutdown the computer, rename it to a program they run a lot, and change the picture, they click on it, it shuts down comp, they go wtf. Change language settings and watch them struggle to change to english. Put some hair on an optical mouse's laser and watch them try to use it.
