Is it a Virus?
✔ NO - Safe
Must be in C:\Program Files\Sunburst\Sunburst.exe or C:\Program Files (x86)\Sunburst\Sunburst.exe
Warning
Many sunburst processes may run
Each data task or pipeline can spawn its own worker process
Can I Disable?
✔ YES
Shut down via Sunburst UI or stop the Sunburst service; do not disable permanently if you rely on Sunburst workloads
What is sunburst.exe?
sunburst.exe is the executable for the Sunburst Data Processing Suite. It coordinates data workflows, transforms, and analytics across modules, and runs as a background service or per-user process as tasks are dispatched. You may see multiple sunburst.exe instances under load.
This multi‑process architecture isolates heavy data tasks for stability and parallel processing. Sunburst launches worker, orchestrator, and ETL components as separate processes, enabling scalable analytics without blocking the user interface.
Quick Fact: Sunburst pioneered modular, multi‑process data pipelines to improve throughput and reliability in enterprise analytics.
Types of Sunburst Processes
- Orchestrator Process: Coordinates pipelines, job scheduling, and task dispatch (1+ instances)
- Worker Process: Executes individual data tasks or steps within a job (multiple instances)
- ETL Processor: Extract-Transform-Load components for data ingestion
- Query Engine: Analytic query execution against datasets
- Streaming Agent: Processes streaming data inputs in real time
- Background Service: Scheduler, log collector, and maintenance tasks
Is sunburst.exe Safe?
Yes, sunburst.exe is safe when it's the legitimate file from Sunburst Technologies downloaded from official sources (sunburst.io or enterprise distribution).
Is sunburst.exe a Virus or Malware?
The real sunburst.exe is NOT a virus. However, malware sometimes disguises itself using similar names to trick users.
How to Tell if sunburst.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\Sunburst\Sunburst.exe or C:\Program Files (x86)\Sunburst\Sunburst.exe. Any sunburst.exe elsewhere is suspicious.
- Digital Signature:: Right-click the process in Task Manager → Open file location → Right-click sunburst.exe → Properties → Digital Signatures. Should show "Sunburst Technologies".
- Resource Usage:: Normal usage is 2-15% CPU per task, 60-180 MB total memory during typical workloads. Extremely high usage when idle is suspicious.
- Behavior:: Sunburst should only run when tasks are scheduled or the UI is active. Continuous background activity when idle may indicate malware.
Red Flags: If sunburst.exe is located in unusual folders (like Temp or AppData), runs when the system is idle, has no valid digital signature, or uses excessive resources constantly, scan your system with reputable antivirus software. Watch for similarly named files such as "sunburstx.exe" or "sunburst_service.exe" from untrusted sources.
Why Is sunburst.exe Running on My PC?
sunburst.exe runs to manage and execute Sunburst workloads, coordinate pipelines, and support background processing for analytics. It may start as a service or per-user task when Sunburst workloads are active.
Reasons it's running:
- Active Data Workloads: You have Sunburst jobs or pipelines currently processing data, causing orchestrator/worker processes to run.
- Background Task Scheduling: Sunburst schedules recurring ETL and maintenance tasks that run in the background.
- Startup and Service Configuration: Sunburst may be configured to start automatically on login or at system boot.
- Live Data Ingestion: Streaming connectors or batch imports keep worker processes engaged while data arrives.
- UI/Client Activity: When the Sunburst UI is open, related processes may run to service requests and analytics queries.
Can I Disable or Remove sunburst.exe?
Yes, you can disable sunburst.exe. It's safe to close Sunburst workloads when not in use, and you can uninstall Sunburst if you no longer require it.
How to Stop sunburst.exe
- End Active Tasks: In Sunburst UI, cancel running jobs or pause pipelines to reduce activity.
- Exit UI: Close the Sunburst client to stop local processes associated with the session.
- Stop Services: Open Windows Services (services.msc), locate Sunburst Service, and Stop it.
- Disable Startup: Task Manager → Startup tab → Disable Sunburst or Sunburst Service.
- Stop Background Apps: In Sunburst Settings → System, disable background task execution if applicable.
How to Uninstall Sunburst
- ✔ Windows Settings → Apps → Apps & Features → Sunburst → Uninstall
- ✔ Control Panel → Programs → Uninstall a program → Sunburst → Uninstall
- ✔ If recommended, remove related components: Sunburst Agent, Sunburst Service, and data directories
Common Problems: High CPU or Memory Usage
If sunburst.exe is consuming excessive resources:
Common Causes & Solutions
- Too Many Active Jobs: Queue grows with multiple concurrent pipelines. Pause or cancel nonessential jobs and stagger schedules.
- Resource-Heavy Data Transformations: Optimize ETL steps, batch large transforms, or increase worker pool capacity.
- Malfunctioning Plugins: Disable suspicious or outdated plugins in Sunburst settings and update to latest versions.
- Outdated Sunburst Version: Update to latest Sunburst build to receive performance fixes and improvements.
- Misconfigured Scheduling: Review cron-like schedules to avoid overlapping heavy jobs.
- Hardware Acceleration Issues: If applicable, toggle hardware acceleration in Sunburst settings or system GPU drivers.
Quick Fixes:
1. Quick Fixes:
2. 1. Open Sunburst Task Manager to identify heavy tasks
3. Pause or cancel nonessential jobs
4. Disable unnecessary plugins in Sunburst settings
5. Update Sunburst to the latest version
6. Review and adjust scheduling to avoid overlaps
Frequently Asked Questions
Is sunburst.exe a virus?
No, the legitimate sunburst.exe from Sunburst Technologies is not a virus. Verify the file is located in C:\Program Files\Sunburst\Sunburst.exe or C:\Program Files (x86)\Sunburst\Sunburst.exe and has a valid digital signature from Sunburst Technologies.
Why is sunburst.exe using so much CPU?
High CPU usually stems from heavy data transformations, large workloads, or overlapping scheduled jobs. Use Sunburst Task Manager to identify workloads and optimize or stagger them.
Can I delete sunburst.exe?
Uninstall Sunburst through Windows Settings or Control Panel if you no longer need it. You will lose access to Sunburst workloads unless you reinstall later.
Can I disable sunburst.exe?
Yes. You can stop Sunburst services and disable startup to prevent automatic launching, but only do this if you do not require ongoing data processing workloads.
Why does sunburst.exe start at login?
Sunburst may be configured to start at login to ensure live data processing and timely task scheduling. Disable startup in Task Manager if not needed.
There are multiple sunburst.exe processes. Is that normal?
Yes. Sunburst uses a multi-process architecture where orchestrator, worker, and ETL tasks run in separate processes to improve performance and fault isolation.
