Verdict Suspicious

Analyzed , 3 months ago

Is harver-system-checker.exe safe? Treat it as suspicious.

The file is signed by Harver B.V. but lacks established reputation.

Why Suspicious? One antivirus engine (Dr.Web) flags it; nothing else confirms it.

Limited evidence

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

Treat as suspicious. Verify the source of the file and monitor its behaviour in a restricted environment.

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

Our analysis shows a signed file with rare prevalence and complex behavioural patterns. The mixed signals from similar hashes further support a cautious classification. We recommend treating this file as suspicious until further evidence of malicious intent is observed.

Where this verdict could be wrong2 caveats
  • The file is signed by a valid corporate entity, which often accounts for complex installation behaviours that trigger rule-based alerts.
  • The lack of malicious hits in our URL/IP cache and the absence of malicious files it created suggest the file may be benign despite its complex behaviour.

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: Ran commands or a script on the test computer.

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

  • 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.

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 recording keystrokes; no keylogging was confirmed.

  • Not confirmed: A sandbox rule tagged this run as creating a service; no new service was recorded.

  • Not confirmed: A sandbox rule tagged this run as setting up auto-start; no auto-start entry was recorded.

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.

What should I do if I already ran harver-system-checker.exe?
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.
Is harver-system-checker.exe digitally signed?
Yes. harver-system-checker.exe has a valid digital signature from Harver B.V., which shows the file hasn't been changed since that publisher signed it. Malware is sometimes signed with stolen certificates, so a signature alone isn't proof of safety.
What is the SHA-256 hash of harver-system-checker.exe?
The SHA-256 fingerprint of harver-system-checker.exe is 4ffc6e789f9f35d313ef3ed75b44bab98240da082a0f700a3ab99d951b931df3, and its MD5 is 506f3f725b514151736d25cf10610fce. 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 harver-system-checker.exe?
This report reflects the scan on Jul 23, 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.
