Good practice2 tips
We found nothing harmful in this file.
Run it only if it came from the developer's own website or an official app store.
Keep your antivirus and Windows updates switched on.

Why we think so
4 points against it and 5 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Filename and tags suggest a legitimate security tool, with behaviour limited to techniques common in legitimate software including Cloudflare contact. No malicious evidence from the test run supports a false positive call.
The detection profile shows minimal flags from non-major antivirus engines with generic labels, a hallmark of rule-based false positives on security tools. Filename 'AiDefend.exe' and analysis flags confirm security software resemblance. Behavioural signals like direct Cloudflare IP contact trigger a rule but align with common app patterns, lacking offensive MITRE or sandbox malice. Unsigned status and rarity add minor risk, but clean major consensus and no corroborating intel outweigh them.
What We Detected
Three engines flagged: Elastic (smaller, generic malicious), huorong (smaller, Ransom/Filecoder.c), alibabacloud (low_trust, Trojan:Win/Lakaboy.LY). All 17 major antivirus engines clean.
Threat Behavior
MITRE techniques common in legitimate software only (system discovery, network protocols, virtualization check). No offensive tactics, no malicious sandbox outcome, one unknown file it created. Tags indicate debug-environment detection, typical for anti-malware.
What To Do Now
Safe per our analysis; verify download source. Run in sandbox if concerned about unsigned nature.
Where this verdict could be wrong2 caveats
- huorong 'Ransom/Filecoder.c' (smaller) label raises ransomware concern, but contradicted by 17 major cleans and no offensive MITRE techniques.
- Unsigned with 'detect-debug-environment' tag and T1497 (virtualization evasion) in behaviour — possible malicious anti-analysis, but no sandbox malicious verdict.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 17/17 major antivirus engines clean
- No major malicious or family consensus
- No offensive MITRE techniques (no offensive techniques were mapped)
- No malicious sandbox verdict
- No malicious files it created or contacted hosts
- Unsigned executable (the file is unsigned)
- rare and prevalence (1 submission, age 7 days)
- detect-debug-environment tag + virtualization technique
- No historical signer stats or similarHashes RAG
