Why Suspicious? 14 antivirus engines flag it and a test run recorded behaviour typical of malware.

Moderate evidence · More than one sign points to a problem, but nothing confirms it is harmful.

Don't run it until you know where it came from

If it came from a link, an attachment or a stranger, delete it.

What to do now4 steps

Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.

What to do

  1. Don't run it unless you're sure where it came from.

  2. Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.

  3. If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.

If you already ran it

  1. Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

Not sure what to do?

Ask the MalwareTips community before you run it. If you already ran it, follow the cleanup guide.

MT AI Engine · Verdict analysis

The reasoning behind this verdict

Analyst conclusion

Microsoft and Symantec are among 14 of the 67 antivirus engines that checked it flagging this unsigned executable, and its sandbox data maps to four injection-related techniques. A clean sandbox verdict, fully checked contacts, and absent family consensus temper the finding, but execution should be avoided pending trusted provenance.

Where this verdict could be wrong4 caveats
  • The only completed sandbox run returned a clean verdict and identified no injected target process.
  • The host-reputation check covered both observed domains and found neither in the malicious or suspicious cache.
  • No malware-specific YARAify rule, MalwareBazaar record, malicious file it created, packing indicator, or strong family consensus was found.
  • Thirteen major antivirus engines did not flag the sample, while the two major detections used generic or machine-learning labels.

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

  • High concern: Injected code into another program on the test computer.

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

  • Note: Listed the programs running on 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.

  • Note: Checked which security software was installed on the test computer.

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

  • Not confirmed: A sandbox rule tagged this run as loading code in memory; 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.

No infection is confirmed: the rating is a caution, not a malware finding. 1) Check where it came from. If you can't confirm the source, delete it. 2) Run a full scan with your security software. 3) If the scan finds something, follow its removal steps and change passwords you typed on the device since then.
What is the SHA-256 hash of hw2_loader.exe?

How up to date is this analysis of hw2_loader.exe?
This report reflects the scan on Oct 16, 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.
