What is arc.exe?

arc.exe is the Windows executable for Arc, a Chromium-based browser designed to boost productivity with a fresh UI, Spaces for organizing work, and lightweight workflows. Arc runs as several processes to keep sessions synced and notifications delivered.

Arc uses a multi-process architecture: a Browser Process, Renderer Processes per tab, a GPU Process for graphics, plus Extension and Utility Processes to isolate features and security boundaries.

Quick Fact: Arc introduced workspace-focused browsing, grouping tabs into Spaces to help you manage projects without clutter.

Types of Arc Processes

Browser Process: Main Arc window and user interface (1 instance)
Renderer Process: Each tab and iframe (multiple instances)
GPU Process: Hardware-accelerated rendering and compositing
Extension Process: Each installed extension gets its own process
Plugin Process: For built-in viewers or plugins like PDF
Utility Process: Background tasks and network services

Is arc.exe Safe?

Yes, arc.exe is safe when it's the legitimate file from The Browser Company downloaded from official sources (official Arc installer or Microsoft Store if distributed there).

Is arc.exe a Virus or Malware?

The real arc.exe is NOT a virus. However, malware can mimic names; always verify the file path and signature.

How to Tell if arc.exe is Legitimate or Malware

File Location:: Must be in C:\Program Files\Arc\Arc.exe or C:\Program Files (x86)\Arc\Arc.exe. Any arc.exe elsewhere is suspicious.
Digital Signature:: Right-click the process in Task Manager → Open file location → Right-click Arc.exe → Properties → Digital Signatures. Should show a valid signature from "The Browser Company".
Resource Usage:: Normal usage is 4-25% CPU per tab, 120-450 MB total memory. Extremely high usage when Arc is closed is suspicious.
Behavior:: Arc should only run when you open the browser. Multiple instances when Arc is closed indicates malware.

Red Flags: If arc.exe is located in unusual folders (like Temp, AppData, or System32), runs when Arc isn’t open, has no valid signature, or uses excessive resources constantly, scan with antivirus. Beware of similarly-named files like "arcw.exe" or "arc32.exe".

Why Is arc.exe Running on My PC?

arc.exe runs when you open the Arc browser or when Arc is configured to run in the background to keep sessions synced and notifications delivered.

Reasons it's running:

Active Browser Use: You're using Arc—each tab and workspace spawns separate renderer and auxiliary processes.
Background Workspaces and Sync: Arc maintains workspaces and syncs data across devices, which can keep processes active even with tabs closed.
Startup Program: Arc can be set to launch automatically when Windows starts for quick access.
Background Extensions: Extensions or Integrations may run in background to provide features like notes or reminders.
Notifications and Background Tasks: Arc performs background checks for updates, notifications, and content indexing.

Can I Disable or Remove arc.exe?

Yes, you can disable arc.exe. It's safe to close Arc when not in use, and you can uninstall it if you prefer another browser.

How to Stop arc.exe

Close Arc: Quit Arc from the system menu or press Alt+F4 to close all Arc windows.
End Arc Process: Open Windows Task Manager (Ctrl+Shift+Esc), locate arc.exe, right-click → End Task
Prevent Startup: Task Manager → Startup tab → Disable Arc Browser
Disable Background Tasks: Arc Settings → General or Preferences → Disable background sync and background apps
Lock Extensions: Review and disable any extensions causing background activity

How to Uninstall Arc

✔ Windows Settings → Apps → Apps & Features → Arc Browser → Uninstall
