There are many threats that can negatively impact computers, including computer viruses, power fluctuations, dust, and rodents. Viruses can harm hardware and software similar to diseases in humans. It is important to use antivirus software and keep it updated to disinfect viruses. Power fluctuations from unstable electricity can damage computers, so using an UPS is recommended. Dust buildup can prevent cooling fans from working properly and overheat systems. Rodents entering computers can severely damage motherboards. Prolonged computer use can also threaten users' posture, vision, and waist health if proper ergonomics are not followed. Users have ethical responsibilities regarding copyright, privacy, and other legal computer uses.
