To securely handle file uploads and prevent malware on your site, you should validate file types, scan for malware, and implement strict access controls.

Example Concept: Secure file upload handling involves validating the file type by checking the MIME type and file extension, scanning files for malware using antivirus software, and storing files in a non-executable directory. Additionally, implement size limits and use secure file naming conventions to prevent overwriting and path traversal attacks.

Additional Comment:

Always validate the file type on both client and server sides to prevent spoofing.
Use a reputable antivirus API to scan files before processing or storing them.
Store uploaded files in a directory with no execute permissions to mitigate the risk of executing malicious files.
Limit file upload size to prevent denial of service attacks.
Regularly update your security tools and libraries to protect against new threats.
