Reputable file providers publish MD5, SHA-1, or SHA-256 checksums alongside their downloads. Use a free tool like HashTab or the built-in command prompt in Windows ( certutil -hashfile filename.bin MD5 ) to ensure your downloaded file matches the source exactly. A mismatch means the file is corrupted or malicious. Scan for Malware

Official distributors often provide an MD5, SHA-1, or SHA-256 hash value next to the download link. After downloading the file, use a tool like Windows PowerShell or Terminal to calculate the file's hash. If the hashes do not match perfectly, the file has been altered and is unsafe.
