Quick Answer

rubymine.exe is safe. It is the official RubyMine IDE executable from JetBrains, launching the UI and background services for Ruby development.

Is it a Virus?

✔ NO - Safe

Must be in C:\Program Files\JetBrains\RubyMine 2025.3\bin\rubymine64.exe or rubymine.exe

Warning

Multiple processes

RubyMine uses separate processes for the IDE, indexing, and plugins

Can I Disable?

YES

Close the IDE to stop rubymine.exe; you can disable startup in Windows if desired

What is rubymine.exe?

rubymine.exe is the executable that starts JetBrains RubyMine, the Ruby-focused IDE. It launches the main UI, editors, and tool windows, then spawns background tasks for indexing, code analysis, and plugin services.

RubyMine employs a multi-process architecture to keep editing responsive: a main IDE process, indexing/background tasks, and plugin isolation. This separation improves stability and allows long-running tasks to run without freezing the UI.

Quick Fact: RubyMine optimizes Ruby coding with background workers that index and analyze code as you work.

Types of RubyMine Processes

Main IDE Process: UI, editors, and project model (1 instance)
Indexer/Background Process: Code analysis and indexing tasks running in background
Plugin Process: Isolated execution for installed plugins
Debugger/Runner Process: Ruby application run/debug sessions
File Watcher/Compiler Process: Watches file changes and runs on-demand tools
Helper/Support Process: Auxiliary services like VCS integration

Is rubymine.exe Safe?

Yes, rubymine.exe is safe when it comes from JetBrains and is installed from jetbrains.com or via an official vendor.

Is rubymine.exe a Virus or Malware?

The legitimate rubymine.exe is not a virus. Malware may disguise itself with similar names.

How to Tell if rubymine.exe is Legitimate or Malware

File Location: Must be in C:\Program Files\JetBrains\RubyMine 2025.3\bin\rubymine64.exe or C:\Program Files\JetBrains\RubyMine 2025.3\bin\rubymine.exe. Any rubymine*.exe elsewhere is suspicious.
Digital Signature: Right-click the file in Explorer → Properties → Digital Signatures. Should show "JetBrains s.r.o." as signer.
Resource Usage: During idle typically modest CPU/memory; indexing can spike CPU to higher levels temporarily.
Behavior: RubyMine should launch when you start the IDE; multiple unrelated rubymine processes without UI could indicate malware.

Red Flags: If rubymine.exe is located in unusual folders (Temp, AppData, or System32), runs without launching the IDE, has no digital signature, or uses constant high resources, run a full antivirus scan. Look for similarly-named files like "rubymine.exe.exe".

Why Is rubymine.exe Running on My PC?

rubymine.exe runs when RubyMine is started or when the IDE performs background tasks such as indexing or testing.

Reasons it's running:

Active RubyMine Use: You are actively editing or running RubyMine projects; the IDE keeps necessary processes alive.
Background Indexing and Analysis: RubyMine indexes code and analyzes syntax and references in the background.
Project Startup or Open: Opening a project or creating a new one launches the IDE processes.
Background Tasks: VCS operations, code inspections, and test runs may keep processes active.
Startup on Boot: If configured, RubyMine can launch on Windows startup, keeping rubymine.exe resident.

Can I Disable or Remove rubymine.exe?

Yes, you can disable rubymine.exe. Quitting the IDE stops the process; you can uninstall RubyMine if you no longer need it.

How to Stop rubymine.exe

Close RubyMine: Use File > Exit or click the X to stop the IDE.
End Process: Open Task Manager, locate rubymine64.exe or rubymine.exe, and End Task.
Disable Startup: Task Manager > Startup tab > Disable JetBrains RubyMine
Disable Background Tasks: Within RubyMine, go to File > Settings > Appearance & Behavior > System Settings and disable "Start RubyMine on system startup" or Background tasks

How to Uninstall RubyMine

✔ Windows Settings -> Apps -> Apps & features -> RubyMine -> Uninstall
✔ JetBrains Toolbox (if used) -> RubyMine -> Uninstall
✔ Consider re-installing other JetBrains IDEs if desired

Common Problems: High CPU or Memory Usage

If rubymine.exe consumes excessive resources, try the following fixes.

Common Causes & Solutions

Large project indexing: Wait for indexing to complete; allow background tasks; check indexing progress in Event Log
Insufficient memory: Increase JVM heap size in bin/rubymine64.vmoptions; allocate more RAM if possible
Resource-heavy plugins: Disable or remove plugins; go to Plugins menu and disable unused ones
Multiple open editors: Close unused editors; use editor tabs efficiently; enable Power Save Mode
Antivirus scanning: Exclude RubyMine bin and project folders from real-time scanning
Outdated RubyMine version: Update to latest version via Help > Check for Updates

Quick Fixes:
1. Open RubyMine Task Manager (Help > Find Action > “Task Manager” or use OS Task Manager to identify heavy processes)
2. Restart RubyMine
3. Invalidate Caches / Restart (File > Invalidate Caches) and re-index
4. Update RubyMine to the latest version
5. Disable unused plugins

Frequently Asked Questions

Is rubymine.exe a virus?

No, rubymine.exe from JetBrains is not a virus. Ensure the file is located under C:\Program Files\JetBrains\RubyMine 2025.3\bin and has a valid signature from JetBrains s.r.o.

Why is rubymine.exe using so much CPU?

High CPU usually happens during indexing or running tests. Use the IDE's built-in Task Manager to locate heavy tasks and pause indexing if possible.

Can I delete rubymine.exe?

Yes, you can uninstall RubyMine from Windows Settings or JetBrains Toolbox. Your projects stay on disk; you may need to reconfigure path when reinstalling.

Can I disable rubymine.exe?

Yes, closing RubyMine stops the main process. To prevent startup, disable it in Task Manager > Startup.

Why does RubyMine start on boot?

If configured, RubyMine may start on Windows startup to provide quick access to projects. Disable this in Task Manager > Startup or in RubyMine settings.

Why are there so many rubymine processes?

RubyMine uses separate processes for UI, indexing, plugins, and runners to improve stability. You can verify with Task Manager or the IDE's diagnostic tools.
