Like this one Customer: "I need you to tell me what browser I am using. Is it Netscape 2.0? The reason I need to know is that I have read that Netscape 2.0 distributes a virus called Java." A guy came into my office, in a real panic. He kept saying something about how his computer screen was shaking violently, and he thought it had a virus! Going down to the computer, I found that the picture on the screen was indeed shaking a lot, but I also noticed something else...a desk fan was placed right next to the monitor, which was plugged into the same power strip. I switched the fan off, and the picture stopped shaking. I told him to move the fan away from the monitor in future, to avoid that problem. Later on I heard him telling a colleague that his desk fan had a virus, and he had to keep it away from the screen to stop it from infecting his computer.
