The reasoning behind this verdict

Analyst conclusion

Unsigned 31-day-old installer with no prior clean history.

Where this verdict could be wrong2 caveats
  • contactedHosts.maliciousHosts.length=0 and behaviour.hasMaliciousSandboxVerdict=false — no prior malicious host cache hits or sandbox consensus.
  • The file is moderately common and file age=31 days could indicate a new but non-malicious installer; however major consensus and offensive MITRE techniques outweigh this.

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

Threat context

How bundlers and adware work

This is a bundler: a real-looking installer that hides extra software inside. When you run it, it installs things you never asked for, such as ad injectors, browser toolbars or fake 'PC cleaner' apps. The people behind it get paid for every app it installs.

Bottom line:It is not usually built to destroy files, but it slows the PC, floods it with ads and can be hard to remove completely.

Questions & answers

What is Setup.exe?
Setup.exe is a software installer, about 4.6 MB. It carries no version information saying what it is or who made it. VirusTotal first saw it on Jun 6, 2026.
How many antivirus engines detected Setup.exe?
28 of the 70 antivirus engines that checked it flag Setup.exe, including Kaspersky and ESET. We weigh which engines flagged it and what else the scan found, not just the count. The rating comes from all the evidence together, not from this count alone.
What should I do if I already installed Setup.exe?
1) Uninstall it, and any program you don't recognise that arrived at the same time, from Settings > Apps (or Control Panel > Programs). 2) Remove browser extensions you didn't add and reset your browser's home page, new-tab page and search engine if they changed. 3) Run a scan with your antivirus to catch anything bundled with it. It is unwanted software rather than an infection, so you don't need to disconnect the device, change passwords or reinstall anything unless the scan finds real malware.
How do I remove Setup.exe?
To remove Setup.exe: 1) uninstall it from Settings > Apps (or Control Panel > Programs), together with anything installed alongside it. 2) Remove unfamiliar browser extensions and reset browser settings it changed. 3) Delete it, then empty the Recycle Bin. 4) Run a scan with your antivirus and remove what it finds.
What kind of program is Setup.exe?
Antivirus engines classify Setup.exe as unwanted software: adware or a bundled program that installs things you didn't ask for.
What is the SHA-256 hash of Setup.exe?
The SHA-256 fingerprint of Setup.exe is 24100b43cdef8a018bad380d223a2825b8eb33b3e7bcacaae316eefc26a36c1f, and its MD5 is 89131076b31dfff1ac51c6def46f5328. 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 Setup.exe?
This report reflects the scan on Jul 8, 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.
