This signed ad-blocker web installer has no antivirus detections, but one sandbox run judged it malicious while another found it clean, leaving the evidence unresolved.

Read the whole reasonShow less

Why Suspicious? One sandbox test run rated it malicious while another found nothing; 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

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

None of the 71 antivirus engines that checked it flagged this file, and it carries a valid signature from AdBlock Ltd, a publisher without an established track record with us. The sandbox runs disagreed: one returned malicious and another clean, with no corroborating hostile behaviour. The file behaves like a web installer that downloads and installs an MSI package.

Where this verdict could be wrong2 caveats
  • One sandbox run returned a malicious verdict, though no injection target, persistence or other hostile artefact backs it up.
  • Zero detections and a valid signature with installer-like behaviour point toward a legitimate ad-blocker web installer, but the signer has no established history with us.

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: Read the user name of the test computer.

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

  • 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).

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 spreading through USB drives; 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 AdblockForYoutube_AdBlock360.exe safe, or is it malware?
AdblockForYoutube_AdBlock360.exe is rated Suspicious: some signs point to a problem, but nothing confirms it is harmful. No antivirus engine flags it; the caution comes from other evidence, such as who made it, how widely it is used or what it did in a test run. 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 AdblockForYoutube_AdBlock360.exe?
AdblockForYoutube_AdBlock360.exe is a Windows program, about 774.5 kB. Its version information says it is “AdBlock360 Adblock for YouTube™”. The digital signature from AdBlock Ltd checks out. VirusTotal first saw it on Aug 17, 2026.
How many antivirus engines detected AdblockForYoutube_AdBlock360.exe?
None of the 71 antivirus engines that checked it flag AdblockForYoutube_AdBlock360.exe. A clean antivirus result is not proof of safety; the caution comes from other evidence, such as who made it, how widely it is used or what it did in a test run.
I already downloaded and ran AdblockForYoutube_AdBlock360.exe — what should I do?
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 AdblockForYoutube_AdBlock360.exe digitally signed?
Yes. AdblockForYoutube_AdBlock360.exe has a valid digital signature from AdBlock 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 AdblockForYoutube_AdBlock360.exe?
The SHA-256 fingerprint of AdblockForYoutube_AdBlock360.exe is 9aab6d00818bc8ab93945e4d22652e296fb72a283b51b4cf29ce15e02ebf207a, and its MD5 is 15066d55056b5d06d43a4f097838ac3a. 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 AdblockForYoutube_AdBlock360.exe?
This report reflects the scan on Oct 22, 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.
