Is Lоader.zip safe?

Verdict
Malicious

Four tier-1 engines and six additional scanners flag this archive, with repeated Trojan-downloader labels centered on document, RTF, and Agent variants.

Ten of 74 engines detected the archive, including four tier-1 products that repeatedly identify Trojan-downloader or Trojan.Agent content. Although exact family consensus is limited and no completed runtime evidence is available, the independent high-trust detections make opening or extracting it unsafe.

Do not open or extract this archive

Quarantine or delete the archive without extracting it, and keep endpoint protection enabled. If it was opened, perform a full scan and investigate any newly created files or processes.

Analyst conclusion

Ten of 74 engines detected the archive, including four tier-1 products that repeatedly identify Trojan-downloader or Trojan.Agent content. Although exact family consensus is limited and no completed runtime evidence is available, the independent high-trust detections make opening or extracting it unsafe.

Where this verdict could be wrong5 caveats
  • 13 of 17 tier-1 engines did not detect the archive, including Microsoft, BitDefender, Avast, Avira, and Fortinet.
  • engines.tier1FamilyConsensus.strong=false; only one tier-1 engine maps to the normalized 'trojandownloader' family.
  • externalIntel.yaraify.ruleCount=0, externalIntel.circl.hit=false, and externalIntel.malwareBazaar.hit=false.
  • The archive is widely submitted, with prevalence.uniqueSources=3494 and prevalence.timesSubmitted=5844, but prevalence alone does not establish safety.
  • communityComments contain conflicting, unverified assessments and are not treated as authoritative runtime evidence.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Recommended action

Quarantine or delete the archive without extracting it, and keep endpoint protection enabled. If it was opened, perform a full scan and investigate any newly created files or processes.

Threat context

How downloaders work

This file is a delivery vehicle. On its own it can look small and harmless, but its job is to quietly pull down and install the REAL payload — often a stealer, ransomware, or bot — from a server the attacker controls.

Bottom line:Because the dangerous part arrives later, early scans can look cleaner than the threat really is.

8 evidence-based answers
Is Lоader.zip malware?
Evidence-based answer
Yes — Lоader.zip is malicious. Do not open or extract it. Delete this archive from the device, then empty the Recycle Bin or Trash. 10 of 74 antivirus engines flag it (family: TrojanDownloader.Agent). It behaves as a downloader/dropper whose job is to pull additional malware onto the device. If you've already opened or extracted it, see the removal and recovery steps below.
What is Lоader.zip?
Evidence-based answer
Lоader.zip is a compressed archive, about 1 KB. Our analysis identifies it as malicious (family: TrojanDownloader.Agent) — a downloader/dropper whose job is to pull additional malware onto the device. Because a file's name and icon can be faked, the safest way to identify it is by its cryptographic hash (below), not its filename.
How many antivirus engines detected Lоader.zip?
Evidence-based answer
10 of 74 antivirus engines flagged Lоader.zip, 10 of them as outright malicious. The raw count alone does not establish safety or danger; we also weigh which engines flagged it and corroborating behavior, identity, reputation, and rule evidence. The malicious verdict comes from the complete saved evidence, not from this antivirus count by itself.
I already downloaded and opened or extracted Lоader.zip — what should I do?
Evidence-based answer
Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
How do I remove Lоader.zip?
Evidence-based answer
To remove Lоader.zip: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Delete this archive from the device, then empty the Recycle Bin or Trash. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
What kind of malware is Lоader.zip?
Evidence-based answer
Lоader.zip is classified as a downloader/dropper whose job is to pull additional malware onto the device. Engines attribute it to the TrojanDownloader.Agent family. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
What is the SHA-256 hash of Lоader.zip?
Evidence-based answer
The SHA-256 hash of Lоader.zip is 21101aa4c41d85b1ae264c020d4ba96041b1283bb7d629795b80c848b18e0686, and its MD5 is 5213d93e5362ed79fc726dc121c08669. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
How up to date is this analysis of Lоader.zip?
Evidence-based answer
This report reflects the scan run on September 18, 2026. Because a file's hash never changes, the identity of Lоader.zip is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
