Verdict Safe
Is Grammarly
Single less reliable detection on a verified Grammarly-signed installer with classic AV-on-AV false-positive indicators.
Read the whole reasonShow less
Moderate evidence · No engine flags it, but no publisher signature confirms who made it.
Treat as a legitimate Grammarly installer; the single less reliable detection is consistent with known AV-on-AV false-positive patterns for security-related filenames.
Good practice2 tips
We found nothing harmful in this file.
Run it only if it came from the developer's own website or an official app store.
Keep your antivirus and Windows updates switched on.
No scanner can promise a file is 100% safe.

Why we think so
2 points against it and 4 in its favour, checked against the scan evidence.
The reasoning behind this verdict
Only one less reliable engine flagged the file; 17 major antivirus engines reported clean. The filename and signer match a legitimate Grammarly installer pattern that commonly triggers rule-based false positives in other AVs.
The engine profile shows onlyLowTrustFlagging with zero malicious detections from major antivirus engines, aligning directly with the av_on_av_fp_pattern heuristic. Signing is verified under the Grammarly name with no brand mismatch. Medium prevalence and the installer filename further support a benign commercial software interpretation.
What We Detected
74 engines scanned the sample; only VBA32 (less reliable) reported 'suspected of Trojan.Notifier.gen'. 17 major antivirus engines including Avast, AVG, Avira, BitDefender, DrWeb, Emsisoft, ESET-NOD32, F-Secure, Fortinet, GData, Ikarus and Kaspersky returned clean. The file is signed and verified by Grammarly with an installer-style filename.
Threat Behavior
Sandbox observed MITRE techniques T1055 (process injection), T1134 (token manipulation), T1485/T1486 (data destruction), T1543/T1547 (persistence) and direct-IP connections to 14 addresses. No malicious sandbox verdict. No complete contacted-host reputation result was available. These behaviours can appear in complex installers but lack corroborating malicious signals.
What To Do Now
The file matches the expected profile of a legitimate Grammarly installer. If obtained from the official Grammarly website or app store, it can be considered safe. Re-scan with updated definitions or run in a controlled environment if additional caution is required.
Where this verdict could be wrong2 caveats
- If the Grammarly certificate was abused, the verified signer would be misleading — but no brandMismatch and prevalence=medium reduce stolen-cert likelihood.
- Two of our behaviour rules matched (high/medium severity) on and the Windows password store activity — could indicate real malice despite limited evidence.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.
