Dear Amy: How are hackers and viruses able to get into computers? — Zhou, Hubei, China

Dear Zhou: The main way hackers are able to get into people's computers through the Internet is by guessing common usernames and passwords to try to gain access. Using a simple password like “12345” is dangerous. Always choose a strong password that includes uppercase and lowercase letters, numbers and special characters.

Viruses are primarily spread through downloading infected files. To avoid infecting your computer, use an antivirus program to scan anything you download. To learn more, go to www.sciencedaily.com/videos/2008/0407-

Dear Amy: How are magnets made? — Alex, Stanhope, N.J.

Dear Alex: The atoms in materials that can be magnetized are organized into small groups, called domains. When the material is placed in a strong magnetic field, the domains become aligned with the magnetic field, creating a magnet. For more information on magnets, visit www.sciencetech.
