The Wrongman's Fix It Guide: Section 8, Chapter 5, Paragraph 64

Virus in your computer? Assuming you’ve already tried a variety of virus scan and cleansing software applications with limited to no success, try taking the PC or laptop with you on your next flight. Viruses hate solar radiation and airplanes bring you closer to the sun. So, hold it up by the window and you should see the viruses jump out near or around the networking ports or cooling fans. Be sure to give them a piece of your mind as they might stow away in your carry on and try to hop back in during the car ride home. That’s right. Viruses have balls.
