The "4Link Download Purity" feature is an automated link-validation and content-sanitization system designed to ensure that downloaded files and redirected URLs are free from "fluff," trackers, and malicious scripts.
Key Functionalities:
4link integrates multiple AV engines (e.g., ClamAV, Kaspersky, Bitdefender) via the VirusTotal API.
Every uploaded file is scanned in a sandboxed environment.
Files flagged as malicious are blocked and the uploader receives an immediate notification.
