Our call: Is Frostix.exe safe?Malicious
Five tier-1 engines plus two more on the MalwareX family, combined with observed process-injection behaviour, outweigh the lack of signer history.

Intelligence
The saved assessment, checked against the scan evidence and recorded coverage.
The reasoning behind this verdict
This section explains the evidence supporting the verdict and keeps conflicting or missing signals visible.
17 of 74 engines flag the sample, five of them tier-1, converging on the MalwareX family. Runtime evidence shows T1055 process injection and the file is brand new with no established signer reputation.
The combination of tier-1 consensus on a named family, confirmed offensive MITRE technique, and zero prior reputation for both file and signer produces a clear malicious determination. Low-trust detections are present but unnecessary once the tier-1 threshold is crossed. Missing host-reputation data is neutral and does not alter the outcome.
What We Detected
Seventeen of seventy-four engines classify Frostix.exe as malicious. Five tier-1 engines (Avast, AVG, Avira, BitDefender, Emsisoft, ESET-NOD32, F-Secure, GData, Microsoft) report variants of MalwareX or Yogi. Two of those engines explicitly agree on the MalwareX family. The sample is signed by an unknown entity "Font Service Watch" that has no prior history in our records.
Threat Behavior
Dynamic analysis recorded the T1055 process-injection technique. The executable wrote temporary .mp4 files and executed from the user desktop, consistent with common dropper or loader patterns. No external domains were contacted during the observed run.
What To Do Now
Do not execute the file. Keep endpoint protection enabled and submit the sample to your security vendor for additional analysis if further confirmation is required.
Where this verdict could be wrong2 caveats
- signing.verified=null leaves open the possibility of a stolen or misused certificate, but the complete absence of signer history makes this scenario more suspicious than mitigating.
- contactedHosts=null means no host-reputation result is available; if malicious infrastructure existed it would not have been detected by that check.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Tier-1 engine consensus on named malware family
- Observed process-injection technique (T1055)
- Zero signer history
- First-seen file with only two submissions
Block the file at the perimeter and endpoint; treat any copies as confirmed threats.
Behavior
Plain-English impact first, then the observed runtime evidence.
What this file does
Observed actions and their security significance
High concern: Injected code into another process, a technique that can conceal execution.
High concern: Attempted to impair or bypass security controls.
Moderate concern: Contained obfuscated or packed code that makes inspection harder.
Moderate concern: Runs hidden system commands (script or shell).
Moderate concern: Communicated over a common application protocol; malware can use this for command-and-control.
Moderate concern: Checked the environment for virtualisation or analysis tools.
Note: Reads your Windows user-account details.
These are observed capabilities from an isolated analysis. A technique does not prove malicious intent on its own, and the file never ran on your device.
Threat context
How trojans work
A trojan disguises itself as something useful or harmless to trick you into running it. Once open, it does its real job in the background — anything from stealing data to opening a back door or downloading more malware.
Bottom line:The disguise is the whole trick, so a trustworthy-looking name or icon means nothing.

MalwareBazaar, YARAify, and CIRCL hashlookup completed and returned no entries for this hash.
Signatures and behavior heuristics
A community signature or high-severity behavioral heuristic matched. Signatures identify known patterns; heuristics are strong leads but are not proof on their own.
The saved runtime evidence maps this activity to MITRE T1055 (Process Injection). The mapping supports possible process injection, but it does not prove the exact injection method or the operator's intent.

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. 17 antivirus detections make that low prevalence materially relevant, but rarity alone is not proof of malware.

This file is dangerous. Treat it as harmful and remove it.
Don't run this file. Delete this file from the device, then empty the Recycle Bin or Trash.
If you already ran it, disconnect from the internet and start with a full antivirus scan or Microsoft Defender Offline scan. If compromise is suspected or the problem persists, use a reputable second-opinion scanner and follow incident-recovery or clean-reinstall guidance.
If you typed any passwords while it was open, change them from a device you trust.

Safety FAQ
- Yes — Frostix.exe is malicious. Do not run it. Delete this file from the device, then empty the Recycle Bin or Trash. 17 of 74 antivirus engines flag it (family: malwarex). It behaves as a trojan — malware disguised as something harmless to trick you into running it. If you've already run it, see the removal and recovery steps below.
- Frostix.exe is a Windows executable program, about 8.1 MB. Our analysis identifies it as malicious (family: malwarex) — a trojan — malware disguised as something harmless to trick you into running it. Because a file's name and icon can be faked, the safest way to identify it is by its cryptographic hash (below), not its filename.
- 17 of 74 antivirus engines flagged Frostix.exe, 17 of them as outright malicious. The raw count alone does not establish safety or danger; we also weigh which engines flagged it and corroborating behavior, identity, reputation, and rule evidence. The malicious verdict comes from the complete saved evidence, not from this antivirus count by itself.
- Act quickly. 1) Disconnect the device from the internet to stop the malware communicating or spreading. 2) Run a full scan with reputable anti-malware software (such as Malwarebytes) and quarantine everything it finds. 3) Change your important passwords from a DIFFERENT, clean device — many threats log keystrokes or steal saved credentials. 4) If you bank or shop on this device, watch closely for fraud and alert your bank. 5) For a confirmed infection, the most reliable fix is to back up your personal files and reinstall the operating system for a clean start.
- To remove Frostix.exe: 1) restart into Safe Mode (Safe Mode with Networking if you need to download a tool) so the malware doesn't auto-start. 2) Run a full scan with reputable anti-malware software and let it quarantine or delete the detections. 3) Delete this file from the device, then empty the Recycle Bin or Trash. 4) Check your browser extensions, startup items, and scheduled tasks for anything unfamiliar. 5) Reboot and scan again to confirm it's gone. If detections keep coming back, a clean operating-system reinstall is the most dependable cure.
- Frostix.exe is classified as a trojan — malware disguised as something harmless to trick you into running it. Engines attribute it to the malwarex family. Knowing the family matters because it tells you the likely impact — data theft, remote control, file encryption, or unwanted ads — and guides the cleanup.
- Frostix.exe claims a signer of Font Service Watch, but the signature is not verified — an unverified or broken signature can be forged, so it should not be trusted as proof of who made the file.
- The SHA-256 hash of Frostix.exe is 3699565e872eef5dca75a2c01de53d408e64d6656107324ee83574d032875440, and its MD5 is e2f6f6fa2f8dd0c60a32b639c0321c9f. This hash is the file's unique fingerprint — two files with the same SHA-256 are identical. Use it to confirm you're looking at exactly this file (not just one with the same name) when comparing against antivirus databases or a download's published checksum.
- This report reflects the scan run on July 26, 2026. Because a file's hash never changes, the identity of Frostix.exe is fixed — but antivirus coverage improves over time, so a file that looks clean today can pick up detections later (and vice-versa). If you need the latest picture, MalwareTips staff can re-run the analysis from scratch.
