Hackers often disguise dangerous viruses as harmless photos or documents. They name a file something like "invoice.pdf.exe", but because Windows hides extensions by default, you only see "invoice.pdf". Clicking it infects your PC. Showing file extensions allows you to see the true nature of every file before you open it. Here is how to enable this vital security feature.

How to Show Extensions:

1. Open File Explorer: Click on any folder or press Windows Key + E.

2. Access View Settings: * In Windows 11: Click the View button at the top menu, hover over Show, and then click on File name extensions.

   • In Windows 10: Click the View tab at the very top of the window and check the box that says File name extensions.

3. Verify: Look at your files again. You should now see suffixes like .jpg, .docx, or .exe at the end of every filename.

If you ever see a document that ends in .exe, .scr, or .vbs, do not open it—it is likely a virus!
