What is adylkuzz.exe?
adylkuzz.exe is the executable component of the Adylkuzz cryptominer malware. Once present on a Windows machine, it covertly consumes CPU cycles to mine cryptocurrency and can exploit system resources without user consent, often spreading via compromised services.
Adylkuzz typically runs as a background process, employing stealth techniques to minimize detection while connecting to mining pools to submit results. It may install persistence methods and hide behind legitimate service names to avoid scrutiny.
Quick Fact: Adylkuzz gained notoriety for coin-mining campaigns that leveraged other networks; it operates quietly to avoid user attention.
Types of Adylkuzz Processes
- Main Miner Process: Core adylkuzz.exe instance performing mining tasks
- Persistence Service: Service or scheduled task to restart on boot
- Dropper/Loader: Components that deliver the miner payload
- Network Communicator: Subprocesses handling mining pool connections
- Monitoring Helper: Background utilities to check for sandboxing
- Cleanup/Uninstall Guard: Utilities that tinker with logs or temp files to avoid detection
Is adylkuzz.exe Safe?
No, adylkuzz.exe is not safe. If found, treat as malicious and isolate the system. Do not assume legitimacy from random paths.
Is adylkuzz.exe a Virus or Malware?
The real adylkuzz.exe is malware. It is used to mine cryptocurrency without user consent and can propagate to other machines.
How to Tell if adylkuzz.exe is Legitimate or Malware
- File Location:: Check for a suspicious location such as
C:\Windows\System32\adylkuzz.exe or C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup\adylkuzz.exe. Legitimate system files are not named adylkuzz.exe.
- Digital Signature:: Right-click the file in Task Manager or File Explorer → Properties → Digital Signatures. Should not show a Google LLC signature; in most cases, signatures are absent or from unknown entities.
- Resource Usage:: Normal usage is low; sustained high CPU/memory with no legitimate task is suspicious.
- Behavior:: Mining activity or persistence tasks running without user interaction indicate malware.
Red Flags: If adylkuzz.exe appears in unexpected folders (like Temp, AppData, Startup), runs without user action, or uses continuous CPU mining, scan with reputable antivirus software and review startup items.
Why Is adylkuzz.exe Running on My PC?
adylkuzz.exe runs when the mining malware is active, or when persistence mechanisms start after boot. It may also run when a user launches a compromised application or web page.
Reasons it's running:
- Active Cryptomining: The miner is actively using CPU cycles to mine cryptocurrency.
- Startup Persistence: Registry entries or startup folders ensure it restarts after reboot.
- Background Tasks: Mining components or loaders run in the background to maintain mining operations.
- Exploited Systems: It may spread to other machines inside a network, staying active on compromised hosts.
- Network C2/Miner Pools: It maintains connections to mining pools or C2 infrastructure for tasking and updates.
Can I Disable or Remove adylkuzz.exe?
Yes, you can disable adylkuzz.exe. It's a malware component; stopping mining helps, but full removal and system cleanup are recommended.
How to Stop adylkuzz.exe
- End Individual Processes: Open Task Manager (Ctrl+Shift+Esc), locate adylkuzz.exe and related mining processes, and End Task.
- Disable Startup: Task Manager → Startup tab → Disable any entry related to adylkuzz or mining software.
- Terminate Services: Open services.msc, find suspicious service names, and stop/disable them.
- Run Antivirus Scan: Update antivirus definitions and perform a full system scan; quarantine or remove detected items.
- Clean Startup: Clean browser extensions and system start items that may reintroduce mining.
How to Uninstall Adylkuzz Components
- ✔ Run antivirus or anti-malware tools to remove adylkuzz-related files and registry entries.
- ✔ Uninstall any mining-related applications from Settings → Apps.
- ✔ Review startup tasks and disable or delete suspicious entries.
- ✔ Consider a clean OS reinstall if infection is widespread.
Common Problems: High CPU, Network, or System Slowdown
If adylkuzz.exe is active, you may notice resource strain. Below are typical problems and practical fixes.
Common Causes & Solutions
- Continuous mining activity: Close mining processes and remove the malware; reboot and scan with AV.
- Startup persistence: Disable startup entries; update OS and patch vulnerabilities.
- Malicious extensions or loaders: Remove suspicious software and browser extensions; perform malware removal.
- Network usage to mining pools: Block mining pool endpoints at firewall; monitor outbound connections.
- Inadequate defenses: Ensure antivirus is up to date; run full system scan with removal.
- Infected legitimate software bundles: Reinstall OS over time and reimage if needed; avoid untrusted installers.
