Safe Downloading: How to Avoid Harmful Files

Learn how to download software and files safely, spot fake download links, and what to do if you opened something you shouldn't have.

Do

  • ✓ Get software from the maker's official site or an app store.
  • ✓ On an NCU computer, install software from Software Center (Windows) or Self Service (Mac).
  • ✓ Pay attention to browser and antivirus warnings.
  • ✓ Check the file type before you open it.

Don't

  • ✗ Click big “Download” or “Start” buttons in ads. They're often fake.
  • ✗ Download “free” versions of paid software, games, or movies.
  • ✗ Open attachments you weren't expecting, especially .exe, .zip, .html, or .iso files.
  • ✗ Install browser extensions or “helper” tools a website pushes on you.
