Introduction
A completed download is not automatically a trustworthy file. Checking its origin, size, and integrity can help identify damaged or altered files.
Check the Source
Download software and documents from the publisher or an established repository. Confirm the domain and avoid misleading advertisements and pop-ups.
Compare Details
Compare the downloaded file size with the publisher’s information. When a checksum or digital signature is available, use it to verify the file.
Scan Before Use
Keep security software updated and scan installers, archives, and executable files before opening them.
Conclusion
Source verification, checksum comparison, and malware scanning provide useful protection before a file is used.
