If you must inspect the file, use a service like VirusTotal to scan the URL or the file itself against dozens of antivirus engines.

If the download started automatically without your consent, delete the file immediately without extracting it.

These files are a common delivery method for scripts that encrypt your personal data and demand payment for its release.

Websites that host "free" content (movies, game cracks, or textbook PDFs) often use these strings as placeholders. When you click "Download," the site generates a unique link that expires after a short period. Potential Security Risks

Verify if the website you were on is the official source for what you were looking for. If the site looked suspicious or was filled with "Click Here" pop-ups, the file is likely unsafe.

Opening such files can sometimes trigger the installation of unwanted extensions that track your data or change your search engine. Safe Practices
