Analyst conclusion

All 75 engines returned clean. The file is signed by Microsoft Corporation with 12 of 13 prior samples rated safe. While the sample is brand-new and rare, the combination of verified Microsoft signing and clean engine consensus supports a safe determination.

Where this verdict could be wrong2 caveats
  • prevalence.classification=rare_new with ageDays=0 — genuine Microsoft-signed installers are typically widely distributed before appearing in our corpus.
  • similarHashes[3].verdict=suspicious with enginesMalicious=30/75 and family=siggen31 — same imphash framework has hosted malware in the past.

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 is this file?
Evidence-based answer
Lookupper - Screen Translator and Dictionary Installer.exe is a software installer (application/x-msdownload), about 796 KB. Our analysis did not identify a verdict-driving threat signal. It carries a verified digital signature from Microsoft Corporation. A file's name can be reused by different files, so we identify it by its cryptographic hash (below).
How many antivirus engines detected this file?
Evidence-based answer
None — 0 of 75 antivirus engines flagged Lookupper - Screen Translator and Dictionary Installer.exe. That's reassuring, though it is not proof that a file is safe, so we also weigh its behaviour, identity, and reputation.
Is this file digitally signed?
Evidence-based answer
Yes — Lookupper - Screen Translator and Dictionary Installer.exe carries a valid digital signature from Microsoft Corporation, 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.
What is the SHA-256 hash of this file?
Evidence-based answer
The SHA-256 hash of Lookupper - Screen Translator and Dictionary Installer.exe is 675771aa5b1037ed44cf79e03b7ebabc030b7c076d1238b6f704bdeb8d173815, and its MD5 is af1c5a13f835b3efc3222806f16b5d43. 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.
Is it safe to install this file?
Evidence-based answer
Based on the recorded evidence, Lookupper - Screen Translator and Dictionary Installer.exe has a low observed risk 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, verify the source and the exact hash before overriding the warning.
How up to date is this analysis of this file?
Evidence-based answer
This report reflects the scan run on September 6, 2026. Because a file's hash never changes, the identity of Lookupper - Screen Translator and Dictionary Installer.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.
