Use a tool like ANY.RUN to open the file in a "disposable" virtual computer. This lets you see what the file does without risking your actual device.
If you must know what is in the file (e.g., for work), use these secure methods:
Upload the file or its download link to VirusTotal or Filescan.io . They check the file against dozens of antivirus engines at once.
Right-click the file, select Delete , and then Empty your Recycle Bin . 🔍 How to Check for Safety
If you haven't clicked the link yet, close the tab or window.
If the file is already in your Downloads folder, do not double-click it . Simply downloading a .zip is usually safe, but opening it or running files inside triggers the infection.
