Is Invitation.exe safe? Treat it as suspicious.

An unsigned, installer named like an invitation that silently installs the FleetDeck remote-access agent, flagged by 22 of the 71 antivirus engines that checked it including five…

Read the whole reasonShow less

Why Suspicious? 22 antivirus engines flag it and one of our detection rules matched it.

Moderate evidence · More than one sign points to a problem, but nothing confirms it is harmful.

Don't run it until you know where it came from

Do not run this file unless your own IT team confirmed sending it; if it already ran, remove the FleetDeck Agent and scan the system with protection enabled.

What to do now5 steps

Some signs point to a problem, but nothing confirms it is harmful. Treat it with caution.

What to do

  1. Don't run it unless you're sure where it came from.

  2. Check where you got it: an unexpected attachment, a link someone sent you or a re-upload is a red flag.

  3. If you can't confirm where it came from, delete it. If you need the program, download it again from the publisher's own website.

  4. It is only 3 days old. If you're unsure, scan it again in a few days; antivirus engines often catch up on new files.

If you already ran it

  1. Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.

MT AI Engine · Verdict analysis

The reasoning behind this verdict

Analyst conclusion

This program installs the FleetDeck remote-management agent, which gives someone remote control of the computer. Engines such as ESET and Kaspersky label it a remote-admin tool, and the invitation-style name on an unsigned, file matches how attackers trick people into installing remote-access software.

Where this verdict could be wrong2 caveats
  • FleetDeck is a commercial remote-management product, and several engines label it as potentially unwanted rather than a trojan, so an administrator deploying it on purpose would see the same behaviour.
  • No malicious contacted hosts, no malicious dropped files and no injection target were recorded.

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 the test run showed

What the file did on a test computer

Confirmed in the test run

  • Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).

  • Moderate concern: Ran commands or a script on the test computer.

  • Moderate concern: Downloaded a file during the test run.

  • Moderate concern: Stopped a service or program on the test computer.

  • Note: Read the user name of the test computer.

  • Note: Deleted files or logs during the test run (installers often clean up after themselves).

  • Note: Talked to servers over the internet during the test run.

Sandbox labels we could not confirm (common in safe files too)

  • Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.

  • Not confirmed: A sandbox rule tagged this run as creating a service; no new service was recorded.

  • Not confirmed: A sandbox rule tagged this run as setting up auto-start; no auto-start entry was recorded.

  • Not confirmed: A sandbox rule tagged this run as weakening security settings; no setting change was recorded.

This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.

Questions & answers

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

Is Invitation.exe safe, or is it malware?
Invitation.exe is rated Suspicious: some signs point to a problem, but nothing confirms it is harmful. 22 of the 71 antivirus engines that checked it flag it. Don't run it unless you're sure where it came from. If you need the program, download it again from the publisher's own website.
What is Invitation.exe?
Invitation.exe is a Windows program, about 4.4 MB. Its version information says it is “FleetDeck Agent”. Version information is written by whoever built the file, so it is a claim, not proof of who made it. VirusTotal first saw it on Oct 22, 2026.
How many antivirus engines detected Invitation.exe?
22 of the 71 antivirus engines that checked it flag Invitation.exe, including Kaspersky and ESET. We weigh which engines flagged it and what else the scan found, not just the count.
What should I do if I already ran Invitation.exe?
No infection is confirmed: the rating is a caution, not a malware finding. 1) Check where it came from. If you can't confirm the source, delete it. 2) Run a full scan with your security software. 3) If the scan finds something, follow its removal steps and change passwords you typed on the device since then.
What is the SHA-256 hash of Invitation.exe?
The SHA-256 fingerprint of Invitation.exe is 630665bfd44ee182c387145e674f7a46628f80d4f83f2eeb4ad41072c9e65c9d, and its MD5 is be0f8fa8b112f417af278432ea1560bb. 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 Invitation.exe?
This report reflects the scan on Oct 22, 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.
