Verdict Malicious

Analyzed , 14 days ago

Is Loader.exe safe? No, we rate this exact file malicious.

No major antivirus engines identified it, so its exact family is uncertain, but the combined evidence is too strong to treat as a routine false positive.

Moderate evidence · Several antivirus engines agree.

Don't run this file

If you already ran it, follow the steps below.

What to do now4 steps

This file is harmful. Don't run it, and remove it.

If you haven't run it

  1. Don't run this file. Delete it, then empty the Recycle Bin.

If you already ran it

  1. Disconnect the device from the internet, then run a full antivirus scan. Microsoft Defender Offline (Windows Security > Virus & threat protection > Scan options) also finds malware that hides while Windows runs.

  2. If you typed passwords on the device after running it, change them from another device you trust.

  3. If the scan keeps finding it, or the device still acts strangely, scan again with a second-opinion scanner from another company; if that doesn't fix it, back up your personal files and reinstall Windows.

If you already ran it, do these in order.

If you opened or installed it

Avoid banking and sign-ins on that device until it is clean. These free MalwareTips guides walk you through it.

MT AI Engine · Verdict analysis

The reasoning behind this verdict

Analyst conclusion

Six of the 71 antivirus engines that checked it flagged the executable, including two smaller engines, although all major antivirus engines remained silent. More importantly, six malware-specific YARA rules matched patterns involving encoded URLs, anti-VM behavior, a suspicious loader artifact, and ransomware-associated code. The completed sandbox run mapped process injection and defense impairment, but it did not identify an injection target or issue an explicit malicious verdict. The file is unsigned and has no established publisher history to offset these signals. The family labels are inconsistent, so the evidence supports a generic trojan or loader assessment rather than a confident PulsarRAT, DonutLoader, Cobalt Strike, or VECT attribution.

Where this verdict could be wrong3 caveats
  • None of the 71 antivirus engines that checked it' major detections flagged the sample, and there is no major family consensus.
  • The single sandbox run produced no explicit malicious verdict and recorded no dropped files, persistence indicators, or sample network contacts.
  • The malware-specific rules disagree on a family, spanning loader, anti-VM, Cobalt Strike, and ransomware-associated patterns, so the exact family remains uncertain.

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

What the test run showed

What the file did on a test computer

Confirmed in the test run

  • Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).

  • Moderate concern: Checked whether it was running on a test computer.

  • Moderate concern: Hid files or windows on the test computer.

  • Note: Read the user name of the test computer.

  • Note: Read basic details of the test computer, such as its Windows version.

  • Note: Looked through folders on the test computer (most installers do this).

  • Note: Loaded extra code modules while running.

Sandbox labels we could not confirm (common in safe files too)

  • Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.

  • Not confirmed: A sandbox rule tagged this run as contacting a server, but no contacted host was recorded.

  • Not confirmed: A sandbox rule tagged this run as weakening security settings; no setting change was recorded.

  • Not confirmed: A sandbox rule tagged this run as changing how Windows loads code; nothing confirms it.

This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.

Threat context

How trojans work

A trojan pretends to be something useful or harmless so that you run it. Once open, it does its real job in the background, from stealing data to opening a back door or downloading more malware.

Bottom line:The disguise is the whole trick, so a trustworthy-looking name or icon means nothing.

Is Loader.exe a virus?
Yes. This copy of Loader.exe (SHA-256 3ea7b88c…ef4d) is malicious. Other files with the same name can be different, so check the hash. Don't run it. Delete it, then empty the Recycle Bin. 6 of the 71 antivirus engines that checked it flag it. Antivirus engines classify it as a trojan: malware disguised as something harmless so that you run it. If you've already run it, see the steps below.
What is Loader.exe?

How many antivirus engines detected Loader.exe?
6 of the 71 antivirus engines that checked it flag Loader.exe, including CrowdStrike and Deep Instinct. We weigh which engines flagged it and what else the scan found, not just the count. The rating comes from all the evidence together, not from this count alone.
What should I do if I already ran Loader.exe?
Act quickly. 1) Disconnect the device from the internet. 2) Run a full scan with your antivirus and let it remove what it finds. 3) Change your important passwords from another device you trust, starting with email and banking, and turn on two-step verification. 4) If you bank or shop on this device, watch your accounts and tell your bank about payments you don't recognise. 5) If the scan keeps finding it, back up your personal files and reinstall Windows.
How do I remove Loader.exe?
To remove Loader.exe: 1) run a full scan with your antivirus and let it remove what it finds. 2) Delete it, then empty the Recycle Bin. 3) Check Settings > Apps, your browser extensions, startup apps (Task Manager > Startup apps) and scheduled tasks for anything you don't recognise. 4) Restart and scan again. If it keeps coming back, scan from Safe Mode with Networking, or back up your files and reinstall Windows.
What kind of malware is Loader.exe?
Antivirus engines classify Loader.exe as a trojan: malware disguised as something harmless so that you run it.
What is the SHA-256 hash of Loader.exe?
The SHA-256 fingerprint of Loader.exe is 3ea7b88c57e7c5642db4c9637f61bfd9d383160b561336e346e3fe3b2cacef4d, and its MD5 is 23536675d00df5b6af8a17933c82985d. Two files with the same SHA-256 are identical, so use it to check you have exactly this file, not just one with the same name.
How up to date is this analysis of Loader.exe?
This report reflects the scan on Oct 12, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.

Other files people checked with the same name, and recent reports with the same rating. A matching name does not make two files the same: only the SHA-256 fingerprint identifies a file.

All file reports
This report and its SHA-256 fingerprint are public, so the next person who checks the same file gets an instant answer; documents and images are listed by type instead of their file name. A file we had not seen before is uploaded to VirusTotal, whose security partners and subscribers can download it; MalwareTips deletes its own copy after the scan. If you ran this file and are worried, scan your device with up-to-date security software.
