Why Suspicious? 12 antivirus engines flag it; nothing else confirms it.

Limited evidence · One sign points to a problem; nothing else confirms it.

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

Avoid running this program unless you trust its source and want what it bundles; if it appeared unexpectedly, uninstall it and run a full scan with your security software enabled.

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.

The reasoning behind this verdict

Analyst conclusion

12 of the 69 antivirus engines that checked it flag this file, mostly as a bundler or potentially unwanted program (BitDefender's engine family and Malwarebytes), with Kaspersky adding a cloud reputation detection. It carries a valid signature from OSAds LTD, a publisher we hold no history for. The sandbox runs showed no high-risk techniques, but the program sent data to two outside web APIs.

Where this verdict could be wrong2 caveats
  • The file has a valid signature and has been seen by 276 different submitters since Dec 11, 2025, which fits a widely distributed commercial bundler rather than a targeted trojan.
  • No high-risk runtime techniques, injection targets or persistence were recorded across the sandbox runs, and none of the contacted hosts are in our malicious cache.

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: Unpacked hidden content while it ran.

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

  • Note: Deleted files or logs during the test run (installers often clean up after themselves).

  • Note: Talked to servers over the internet during the test run.

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

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 weakening security settings; no setting change was recorded.

  • 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.

Questions & answers

Short answers to the 7 questions people ask most about this file.

Is WPFApp.exe safe, or is it malware?
WPFApp.exe is rated Suspicious: some signs point to a problem, but nothing confirms it is harmful. 12 of the 69 antivirus engines that checked it flag it. Don't run it unless you're sure where it came from. If you need the program, download it again from the publisher's own website.
What is WPFApp.exe?
WPFApp.exe is a Windows program, about 7.9 MB. Its version information says it is “WPFApp”. The digital signature from OSAds LTD checks out. VirusTotal first saw it on Dec 11, 2025.
How many antivirus engines detected WPFApp.exe?
12 of the 69 antivirus engines that checked it flag WPFApp.exe, including Kaspersky and Bitdefender. We weigh which engines flagged it and what else the scan found, not just the count.
What should I do if I already ran WPFApp.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 WPFApp.exe digitally signed?
Yes. WPFApp.exe has a valid digital signature from OSAds LTD, 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 WPFApp.exe?
The SHA-256 fingerprint of WPFApp.exe is 6753a63c6ae3b9b045304a464d08617c09af390772c0fbd12579967d48106e14, and its MD5 is 4f3acfa48186363f91ec1c516bae4d2d. 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 WPFApp.exe?
This report reflects the scan on Oct 26, 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.

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.
