✅ Microsoft Defender, Kaspersky, Norton, Avast, AVG, Bitdefender, ESET, Malwarebytes, McAfee — all report CLEAN.

⚠️ Why 4 false positives? ReallyFastDownload includes a built-in anti-reverse-engineering security layer — anti-debugger traps, memory integrity checks, and code obfuscation. Some lesser-known engines (Arctic Wolf, Bkav Pro, CrowdStrike Falcon, SecureAge) cannot analyze this and flag it by mistake. All major engines confirm 100% safe.
