Safe
Legitimate Zemana AntiMalware installer with detections from common security software behaviors flagged as false positives by our antivirus network.
b548f01428cb26a587…7bf23fa965The reasoning behind this verdict
The MT AI Engine weighs every signal from this scan — antivirus detections, sandbox behaviour, code signing, prevalence and historical matches — to reach a single, evidence-based verdict.
Overwhelming majority of tier-1 engines (16/17) report clean, with only generic/tool detections on a signed security installer. Behavioral signals match typical installer actions like temp file extraction and driver setup, not exploitation. High prevalence and age confirm it's established software. Heuristics for injection/IP contact reflect AV self-protection, not threats.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

5 detections across 75 engines
Section entropy & packers
Section-level entropy and packer detection from the PE header. Nothing suspicious here — entropy is within the normal range for unpacked code.
How widely this file has been seen
Widely seen in the wild for a long time. High prior this is legitimate; isolated detections on common-old files are usually false positives.

Safety FAQ
Common questions about Zemana.AntiMalware.Setup.exe, answered from the scan data above.
- Zemana.AntiMalware.Setup.exe appears safe. 70 of 75 antivirus engines report it clean, with only 5 low-confidence detections that read as false positives. It carries a verified digital signature from Zemana D.O.O. Sarajevo. As a habit, only run files you downloaded from the official source, since attackers sometimes distribute trojanised copies of legitimate software under the same name.
- Zemana.AntiMalware.Setup.exe is a Windows executable program, about 13.3 MB. Our analysis found no threat indicators for it. It carries a verified digital signature from Zemana D.O.O. Sarajevo. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
- 5 of 75 antivirus engines flagged Zemana.AntiMalware.Setup.exe, 5 of them as outright malicious. A small number of detections can include false positives, so we weigh which engines flagged it and what else the file does, not just the raw count.
- Yes — Zemana.AntiMalware.Setup.exe carries a valid digital signature from Zemana D.O.O. Sarajevo, which confirms the file hasn't been tampered with since that publisher signed it. A valid signature is a positive signal, but note that malware is occasionally signed with stolen or abused certificates, so it isn't proof of safety on its own.
- The SHA-256 hash of Zemana.AntiMalware.Setup.exe is b548f01428cb26a5870602e8018adbce814dd2ed53a6b1f74c3b3b7bf23fa965, and its MD5 is 048ea3233e0e7611ab414684583c1421. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
- Based on this scan, yes — Zemana.AntiMalware.Setup.exe shows no threat indicators and is properly signed. The important caveat is source: make sure you downloaded it from the official website or a trusted store, because attackers sometimes distribute malware-laced copies under a legitimate file's name. If your own antivirus flags it while we report it clean, that is most often a false positive, but verify the source before overriding your antivirus.
- This report reflects the scan run on May 2, 2026. Because a file's hash never changes, the identity of Zemana.AntiMalware.Setup.exe is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
