The reasoning behind this verdict

Analyst conclusion

The antivirus engines shows 0/71 detections, including all major antivirus engines clean. Behavior matches 7-Zip installation: drops language files and CHM to C:\Program Files\7-Zip\, contacts cert servers. Rules flag installer traits as suspicious but this is a common false positive for self-extracting archives. Safe to use.

Where this verdict could be wrong4 caveats
  • triggeredHeuristics['one of our behaviour rules'] cites access to the Windows password store — Mimikatz-like but common for installers querying system info; no actual dumping observed.
  • communityComments include 'stealer/spyware' tags from one researcher — but outweighed by Joe Sandbox 'CLEAN' verdict and 0 AV detections.
  • signing.signed=false (unsigned) — raises minor concern but CIRCL/prevalence confirm legitimacy.
  • The sandbox's contacted-IP list includes direct IPs (20.99.* Azure-like) — flagged by rule but tied to cert fetches.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Questions & answers

Short answers to the 6 questions people ask most about this file.

Is 7zipInstall.exe safe?
We found nothing harmful in 7zipInstall.exe. None of the 70 antivirus engines that checked it flag it. Run it only if it came from the developer's own website or an official app store.
What is 7zipInstall.exe?
7zipInstall.exe is a Windows program, about 1.6 MB. It carries no version information saying what it is or who made it. VirusTotal first saw it on Jun 20, 2023.
How many antivirus engines detected 7zipInstall.exe?
None of the 70 antivirus engines that checked it flag 7zipInstall.exe. That is a good sign, but not proof, so we also weigh who made it, how widely it is used and what it did in a test run.
What is the SHA-256 hash of 7zipInstall.exe?
The SHA-256 fingerprint of 7zipInstall.exe is 26cb6e9f56333682122fafe79dbcdfd51e9f47cc7217dccd29ac6fc33b5598cd, and its MD5 is e5788b13546156281bf0a4b38bdd0901. 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.
Is it safe to run 7zipInstall.exe?
We found nothing harmful in 7zipInstall.exe. The main caveat is where you got it: attackers sometimes spread malware under the name of real software, so get it from the official website. If your own antivirus warns about it, check the source before you ignore the warning.
How up to date is this analysis of 7zipInstall.exe?
This report reflects the scan on May 12, 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.
