How to check a file on the Internet that it does not have viruses

There are several ways to check a file on the internet for viruses:

  1. Use an online virus scanner: You can use an online virus scanner such as VirusTotal or Jotti’s malware scan to scan a file for viruses. These services scan files with multiple antivirus engines and provide you with a report of any detected threats.
  2. Use your antivirus software: Most antivirus software includes the ability to scan individual files for viruses. Right-click on the file you want to scan and select “Scan with [your antivirus software]”.
  3. Check the file’s digital signature: Some software vendors sign their files with a digital signature to verify their authenticity. Check the file’s properties to see if it has a digital signature and if it is valid.
  4. Check the file’s reputation: If the file has been around for a while, you can search for it on the internet to see if other users have reported it as malicious. Use a search engine and add keywords such as “virus” or “malware” to see if there are any reports of the file being malicious.

It’s important to note that even if a file is scanned and found to be clean, it’s still possible that it could contain a new, undetected virus. Always exercise caution when downloading and running files from the internet, and only download files from trusted sources.
