Is ChatGPT Installer.exe safe?
The verified Microsoft signature, zero detections across 74 engines, and matching signed-installer history strongly support this newly observed installer.
No engine among 74 flagged this executable, while all 17 participating tier-1 engines reported no detection. Its Microsoft Corporation signature verifies, and a signer-co-matched installer received a prior clean assessment, although the file is newly observed and lacks completed runtime analysis.

Before installing
Install it only when it came from the developer's official site or an official app store.
If you already installed it
Keep normal device protection enabled and stop if the file behaves unexpectedly.

The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
No engine among 74 flagged this executable, while all 17 participating tier-1 engines reported no detection. Its Microsoft Corporation signature verifies, and a signer-co-matched installer received a prior clean assessment, although the file is newly observed and lacks completed runtime analysis.
The strongest evidence is the verified Microsoft Corporation signature combined with zero detections across 74 engines. All 17 participating tier-1 engines reported no detection, and there is no family consensus or hacktool labeling. Historical signer data is favorable at 20 of 21 samples, while one signer-co-matched installer with the same imphash also received a clean assessment. Static PE analysis does not indicate packing or high-entropy code, and researcher intelligence produced no matching rules or known-malware records. The file is newly observed, and no sandbox completed execution, so runtime conduct and host reputation remain unconfirmed.
What We Detected
None of 74 antivirus engines flagged the executable, including all 17 participating tier-1 engines. The code signature verifies as Microsoft Corporation, and signing.trustedPublisher.matched confirms Microsoft on the curated publisher list. Signer history is favorable, with 20 of 21 prior samples assessed as clean.
Threat Behavior
Static metadata lists T1620 among the extracted techniques, but behaviour.sandboxCount=0 means there was no completed runtime observation to confirm it. The executable is not identified as packed, high-entropy code was not found, and no malicious child was reported. contactedHosts is unavailable, so no complete host-reputation result can be stated.
What To Do Now
Verify that the installer came from an official Microsoft distribution channel and keep endpoint protection enabled. Because this hash is newly observed, users handling it in a sensitive environment may also confirm the certificate details and rescan after reputation has matured.
Where this verdict could be wrong4 caveats
- prevalence.classification='rare_new' records only 1 submitter and 1 submission, so broad real-world reputation has not yet formed.
- behaviour.offensiveTechniques includes T1620, but behaviour.sandboxCount=0 means it was not confirmed through completed runtime observation.
- signing.signerStats includes 1/21 previously malicious samples and autoTrusted=false, although the present signature verifies and no engine detects this file.
- contactedHosts=null, so no complete host-reputation cross-check is available.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- 0/74 antivirus detections.
- All 17 participating tier-1 engines reported no detection.
- Verified Microsoft Corporation signature.
- Microsoft matched the curated trusted-publisher list.
- No packing, high-entropy code, YARAify rules, or MalwareBazaar record.
- Only 1 submitter and 1 submission are recorded.
- No completed sandbox execution is available.
- Static technique extraction includes T1620.
- No complete contacted-host reputation check is available.
- Signer history contains 1 malicious assessment among 21 samples.
Use the file only if it came from an official Microsoft channel, and keep endpoint protection enabled. The current evidence is strongly reassuring, but the hash is too new to have mature prevalence.

Section entropy & packers
No high-entropy executable section or known packer signature was detected. Data and resource sections can still have high entropy without indicating packed code.
How widely this file has been seen
Barely seen in the wild and first surfaced recently. That limits reputation evidence, but rarity alone is not proof of malware.
