Protecting your personal computer
Answer
Personal computers need to be protected from both physical and software threats.
To protect against theft, we recommend students use a computer cable lock to secure their laptops to a table or desk if they're not in your possession.
For software protection against viruses and malware, Windows 10/11 includes Defender. Other apps are available, both free and for purchase, and your computer may come with one of these pre-installed. Unless you intend to use and maintain this third-party app, be sure Defender is enabled and running on your machine.
