Malicious
Unsigned 0-day PE with strong tier-1 consensus on MalwareX family and no benign signer history.
43e5948b04b8bf800f…7956daaa4aThe reasoning behind this verdict
The MT AI Engine weighs every signal from this scan — antivirus detections, sandbox behaviour, code signing, prevalence and historical matches — to reach a single, evidence-based verdict.
The decisive signal is the tier-1 family consensus on malwarex backed by Avast, AVG, Avira, ESET-NOD32, F-Secure and Ikarus. Absence of signing, zero prevalence, and a brand-new submission date reinforce the malicious classification. Clean sandbox behaviour and lack of contacted hosts are noted but do not override the engine consensus on a rare_new unsigned binary.
Each signal cites a concrete token from the evidence the arbiter saw — engine name, MITRE technique, signer string, or an exact count.
engines.tier1FamilyConsensus: family=malwarex, agreeingEngines=3, strong=true
engines.tier1Malicious=6 (Avast, AVG, Avira, ESET-NOD32, F-Secure, Ikarus, Symantec)
signing.verified=false, signerStats.found=false, prevalence.classification=rare_new
topDetections[2].result=Win64:MalwareX-gen [Cryp] (Avast tier1)
- No sandbox malice detected
- No contacted malicious hosts
- Unsigned binary
- rare_new prevalence
- tier-1 family consensus on MalwareX
Block the hash and avoid execution; the tier-1 consensus on a new unsigned sample outweighs the clean runtime signals.

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.
What to do now
This file is dangerous. Treat it as harmful and remove it.
Don't open or run this file. Delete it from your Downloads (or wherever you saved it), then empty the Recycle Bin.
If you already opened it, disconnect from the internet and run a full scan with your antivirus — Windows Security, built into Windows, is sufficient.
If you typed any passwords while it was open, change them from a device you trust.
In future, only download software from the official website or an official app store.

Section-level entropy and packer detection from the PE header. Nothing suspicious here — entropy is within the normal range for unpacked code.
How widely this file has been seen
Barely seen in the wild and first surfaced recently. This is the footprint of targeted malware the AV industry hasn't signatured yet — extra scrutiny is warranted.

Safety FAQ
Common questions about tolia3o4.j4c.exe, answered from the scan data above.
- Yes — tolia3o4.j4c.exe is malicious, so do not run it, and delete it. 19 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.
- tolia3o4.j4c.exe is a Windows executable program (application/x-msdownload), about 637 KB. 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.
- 19 of 74 antivirus engines flagged tolia3o4.j4c.exe, 19 of them as outright malicious. A detection rate at this level is a reliable signal that the file is dangerous.
- 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 tolia3o4.j4c.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 the original tolia3o4.j4c.exe file and empty the Recycle Bin/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.
- tolia3o4.j4c.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.
- The SHA-256 hash of tolia3o4.j4c.exe is 43e5948b04b8bf800fd19def5f5e3abd5f629206626d8a91e35e187956daaa4a, and its MD5 is 545528c2f40e07b623f7d718a2da5e27. 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 12, 2026. Because a file's hash never changes, the identity of tolia3o4.j4c.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.
