Vivaldi Web Browser
vivaldi.exe is safe. It's the official Vivaldi browser executable using a multi-process architecture to isolate tabs, extensions, and internal tasks for stability and security.
vivaldi.exe is the executable that launches the Vivaldi web browser on Windows. Vivaldi uses a Chromium-based engine with a multi-process architecture, so you may see several vivaldi.exe processes in Task Manager—one per tab, extension, and plugin. This file starts the browser and coordinates core features.
Built on Chromium, vivaldi.exe runs multiple sandboxed processes for tabs, rendering, extensions, and plugins. This separation improves stability and security by isolating failures and reducing cross-process access.
Quick Fact: Vivaldi is built on Chromium and embraces per-tab processes to isolate content, while offering user-focused features and customization.
Yes, vivaldi.exe is safe when it's the legitimate file from Vivaldi Technologies downloaded from official sources (vivaldi.com) or pre-installed by a trusted manufacturer.
The real vivaldi.exe is NOT a virus. However, malware sometimes disguises itself using similar names to trick users.
C:\Program Files\Vivaldi\Application\vivaldi.exe or C:\Program Files (x86)\Vivaldi\Application\vivaldi.exe. Any vivaldi.exe elsewhere is suspicious.Red Flags: If vivaldi.exe is located in unusual folders (like Temp, AppData\Roaming, or System32), runs when Vivaldi isn't open, has no digital signature, or uses excessive resources constantly, scan your system with antivirus software immediately. Beware of similarly-named files like "vivaldi_old.exe" or "vivald.exe" from untrusted sources.
