Overview & Key Terminology

The terms "virus" and "malware" are often used interchangeably. However, they are technically different, so the question of malware vs. viruses is an important one.


Depending on the type of operating system you have, you should have some default antivirus protection but may need to supplement with additional malware protection. 

Windows 10 and 11 Recommendations

  • For Windows 10 computers, we recommend using the built-in Windows Security. Security experts consider it to be a powerful defense against virus and other threats. 3rd party antivirus software is generally not needed on Windows 10 machines.
  • Windows Security is enabled by default on Windows 10 machines, but if you want to make sure it is enabled, simply type Windows Security in the start menu, click on Windows Security, and make sure there is a green checkmark next to all settings as shown below.
  • Always allow Windows updates to run to ensure Windows Security is up to date.

macOS Recommendations

  • Mac computers build on the unique capabilities of Apple hardware and have a system security is designed to maximize the security of the operating systems on Apple devices without compromising usability. System security encompasses the boot-up process, software updates, and the ongoing operation of the OS.
  • Technologies like XD (execute disable), ASLR (address space layout randomization), and SIP (system integrity protection) make it difficult for malware to do harm, and they ensure that processes with root permission cannot change critical system files.
  • As long as your Mac is up to date with the latest operating system, as of March 2020 this is macOS Catalina 10.15June 2021 that is Version 11.0 Big Sur, then your Mac has protection from viruses that can do harm.
  • As a supplemental precaution, we recommend downloading an AdWare/Spyware remover program called MalwareBytes. Any computer that can connect to the internet can get malware but most times it is quickly and easily removed by running an industry standard program like MalwareBytes.

Adblock - Block YouTube ads & help protect yourself from some types of malware

  • Advertisements and popup links on websites may claim to provide a free application app or service, but many times these links are malicious and result in a malware infection.
  • To avoid this risk, and to potentially improve your web-browsing experience by blocking intrusive ads, including YouTube ads, use Mozilla Firefox or Google Chrome as your web browser and install the uBlock Origin ad-blocker addon via one of the links below:
  • While browsing SU websites or any other website you fully trust or may want to support by allowing advertisements, disable uBlock Origin by clicking on it's icon uBlock Origin Icon at the top-right of your browser, then click the "power" icon which will disable it only for the website you are currently visiting.
