Suspicious
This MD5_Hash_Changer.exe is flagged anomalous by one engine (Malwarebytes), but 15 tier-1 engines and most others see it clean—likely a false positive on a hash tool.
99cf802bec942be688…bcecd5b21eThe 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 file is an unsigned Win32 EXE named MD5_Hash_Changer.exe, 142KB, first submitted about 700 days ago with neutral reputation (score 0). Out of 75 engines, only one—Malwarebytes (tier-2)—detects it as 'MachineLearning/Anomalous.95%', a heuristic signal, while 15 tier-1 engines (BitDefender, Kaspersky, ESET-NOD32, etc.) and 64 others say undetected or clean. No tier-1 malicious hits, no external intel from MalwareBazaar or others, and network tags like 'detect-debug-environment' suggest it might evade analysis but don't confirm threats. This single low-confidence flag pattern often means a false positive, especially on tools like hash changers. We rate it suspicious but lean safe—don't run it without verification.
- 15 tier-1 engines (BitDefender, Kaspersky, ESET-NOD32, etc.) report clean.
- 64 engines undetected, no other malicious hits.
- No hits in MalwareBazaar, YARAify, or CIRCL.
- Seen for 700 days without widespread flags.
- No popular threat label from our network.
- Flagged malicious by Malwarebytes as MachineLearning/Anomalous.95% (tier-2 heuristic).
- Unsigned executable with neutral reputation (0).
- Network tag 'detect-debug-environment' suggests anti-analysis tricks.
- File name MD5_Hash_Changer.exe implies hash manipulation, which can be misused.
- Only 75 engines scanned, 6 timeouts.
Quarantine or delete the file immediately. If it's a needed tool, verify from official source and rescan with multiple AVs before use.
What to do now
We couldn't fully clear this file. Treat it with caution.
Don't run it unless you're certain it came from a source you trust.
Check where you got it — an email attachment or a random download link is a red flag.
If you're unsure, delete it. You can always re-download a clean copy from the official source.
If you're still unsure, scan it again in a day or two — detections often catch up on newer files.

Safety FAQ
Common questions about MD5_Hash_Changer.exe, answered from the scan data above.
- MD5_Hash_Changer.exe is suspicious — treat it as unsafe until you're sure. 1 of 75 antivirus engines flag it, which isn't a strong consensus but is enough to be cautious. Don't run it unless you fully trust where it came from, and prefer downloading the software fresh from its official site.
- MD5_Hash_Changer.exe is a Windows executable program, about 139 KB. We identify a file by its cryptographic hash rather than its name, because the same filename can be reused by completely different files — the hash below is the reliable fingerprint.
- 1 of 75 antivirus engines flagged MD5_Hash_Changer.exe, 1 of them as outright malicious. A small number of detections can include false positives, so we weigh which engines flagged it and what else the file does, not just the raw count.
- 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 MD5_Hash_Changer.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 MD5_Hash_Changer.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.
- The SHA-256 hash of MD5_Hash_Changer.exe is 99cf802bec942be688352e3c0ccd1158250bd88cd38ea4cb6c5ef3bcecd5b21e, and its MD5 is ea2d2d6003c858771eec344ac6aa494a. 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 April 20, 2026. Because a file's hash never changes, the identity of MD5_Hash_Changer.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.
