Dear Amy: How does a virus really affect the computers we use? — Raaga, Delray Beach, Fla.

Dear Raaga: What happens to your computer depends on which virus infects it. Some viruses will change program files or delete important files. Other viruses may delete everything on your hard drive. One of the trickiest kinds of viruses is called a “worm.” It is designed to copy itself and spread the virus to other computers. Worms can be spread through e-mail, which is why it is important to protect your computer by installing anti-virus software.

Fine, gold wires are often used in circuits such as on printed circuit boards or to connect circuits to different parts of the computer.
