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.
We couldn't analyse this file — no antivirus engines have scanned it yet. Re-upload the file or try a different sample.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.

What to do now
There isn't enough information to give this file a clear rating.
Be cautious — an unknown rating is not the same as a clean bill of health.
Only run it if it came directly from the official maker of the software.
When in doubt, don't open it — or scan it again later once it's more widely seen.

Safety FAQ
Common questions about PSFLabInstaller-macOS.app.zip, answered from the scan data above.
- We can't give PSFLabInstaller-macOS.app.zip a confident verdict yet — too few engines have an opinion on this exact file. Uncommon or brand-new files often show little coverage before vendors catch up, so treat it as untrusted: don't run it unless you're certain of the source.
- PSFLabInstaller-macOS.app.zip is a software installer (application/zip), about 2.4 MB. We identify a file by its cryptographic hash rather than its name, because the same filename can be reused by completely different files — the hash below is the reliable fingerprint.
- The SHA-256 hash of PSFLabInstaller-macOS.app.zip is 690a81e4241dc71740175f0bef30c48a9092ee9bf515af88949757100be7777b, and its MD5 is fd399556549d3f0240c939b63852f0cf. 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.
- This report reflects the scan run on June 1, 2026. Because a file's hash never changes, the identity of PSFLabInstaller-macOS.app.zip 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.
