In the digital age, cybersecurity is more important than ever. With browsers being one of the most used gateways to the internet, it’s no surprise that threats often sneak in through them. Enter Chromium Virus Scanner OnDemand—a lesser-known but highly valuable feature aimed at helping users stay safe while browsing.
But what exactly is it? Do you need it? And how does it work?
This article breaks down everything you need to know about Chromium Virus Scanner OnDemand, including how it works, when it activates, and whether or not you should worry when you see it running on your system.
What Is Chromium Virus Scanner OnDemand?
Chromium Virus Scanner OnDemand is a built-in feature in Chromium-based browsers (like Google Chrome, Microsoft Edge, and Brave) designed to scan your system for potentially harmful software—especially software that can interfere with browser behavior.
It operates as an on-demand scanner, meaning it doesn’t run constantly like traditional antivirus software. Instead, it runs occasionally or when triggered by suspicious browser activity, such as:
- Repeated pop-ups and redirects
- Hijacked search settings
- Unwanted extensions or toolbars
- Sudden changes in homepage or default search engine
The goal is to help users detect and remove software that could compromise the browser experience or personal data.
Is It a Standalone Antivirus?
No. Chromium Virus Scanner OnDemand is not a replacement for full antivirus software. It’s a lightweight, browser-integrated scan tool, often working alongside features like Chrome’s Cleanup Tool.
Its main purpose is to detect and prompt users about harmful software related to browsing, not system-wide viruses or malware.
Why Does It Show Up in Task Manager?
Many users notice “Chromium Virus Scanner OnDemand” or “Software Reporter Tool” running in Task Manager and worry that it’s a virus itself.
But don’t panic—it’s a legitimate process associated with the Chromium browser project. It may use CPU resources temporarily while scanning but usually doesn’t stay active for long.
What Triggers the Scan?
The scanner can activate:
- On browser startup
- After installing/uninstalling extensions
- If suspicious activity is detected
- When prompted manually via browser settings (e.g., “Clean up computer” in Chrome)
Should You Disable It?
Generally, no. It’s safe, helpful, and built to protect you. However, if you prefer full control over what runs on your system—or if the scanner causes high CPU usage—you can choose to disable it manually.
Keep in mind, disabling it may reduce protection against browser-targeted malware.
How to Disable Chromium Virus Scanner OnDemand (If Needed)
Disclaimer: Disable with caution. Only do this if you’re using another trusted antivirus solution.
Here’s how:
- Press
Win + R, type: shellCopyEdit%localappdata%\Google\Chrome\User Data\SwReporter\ - Find the folder named with a version number (e.g.,
103.264.200). - Delete or rename the
software_reporter_tool.exefile. - You can also deny permissions to the folder so it can’t run again.
Or use Windows Group Policy (for advanced users) to block the Software Reporter Tool from executing.
