You can scan your computer for potentially harmful software that affects Google Chrome directly through the browser's built-in "Clean up computer" feature. This tool helps remove unwanted software that may be interfering with your browser's performance or security.
Scanning for Unwanted Software with Chrome's Built-in Tool
Google Chrome offers a convenient way to find and remove malicious software that might be causing issues like unwanted ads, pop-ups, or changes to your browser settings. Follow these steps to utilize Chrome's scanner:
- Open Google Chrome: Launch the browser on your computer.
- Access the Menu: Click on the three-dot menu icon (⋮) located in the top-right corner of the Chrome window.
- Go to Settings: From the dropdown menu, select "Settings."
- Navigate to Advanced: Scroll down to the bottom of the Settings page and click on "Advanced" to reveal more options.
- Find "Clean up computer": Under the "Reset and clean up" section, click on "Clean up computer."
- Start the Scan: Click the "Find" button to initiate the scan. Chrome will then search for harmful software on your computer that might be affecting the browser. If any unwanted programs are detected, follow the on-screen prompts to remove them.
This process targets specific types of software that Google identifies as potentially harmful or unwanted, often those that piggyback on other installations or alter browser behavior without user consent.
What Chrome's Scanner Does (and Doesn't Do)
Chrome's "Clean up computer" feature is designed to identify and remove software that specifically interferes with the browser. This includes:
- Adware: Programs that display unwanted advertisements.
- Browser Hijackers: Software that changes your homepage or search engine without permission.
- Potentially Unwanted Programs (PUPs): Applications that might have been installed without your full awareness and could impact performance or privacy.
Important Note: While useful for browser-specific issues, this tool is not a comprehensive antivirus solution. It does not scan your entire computer's hard drive for all types of viruses, ransomware, spyware, or other advanced malware.
For Comprehensive Malware Detection: Use Dedicated Antivirus Software
For thorough protection, it's crucial to use a dedicated and reputable antivirus or anti-malware program that can scan your entire system. These tools offer deeper scans and broader protection against a wider range of threats.
Here's a comparison:
| Feature | Chrome's "Clean up computer" | Full System Antivirus Software |
|---|---|---|
| Scope of Scan | Browser-related software | Entire computer (files, drives, memory) |
| Threat Types Detected | Adware, hijackers, PUPs | Viruses, ransomware, spyware, rootkits, adware, PUPs |
| Real-time Protection | No | Yes, continuous monitoring |
| Firewall | No | Often included |
| Purpose | Browser health | Overall system security |
Recommendations for Full System Scans:
- Windows Security (Windows Defender): Built into Windows, it offers robust protection. You can manually run a full scan by searching for "Windows Security" in the Start menu, going to "Virus & threat protection," and then "Scan options."
- Third-party Antivirus: Consider reputable options like Malwarebytes, Avast, AVG, Norton, or Bitdefender for enhanced features and protection across different operating systems.
- Regular Scans: Make it a habit to run full system scans regularly (e.g., weekly or monthly) to catch any threats that might have bypassed real-time protection.
Preventing Malware and Unwanted Software
Proactive measures are key to keeping your computer safe from malware.
- Keep Software Updated: Regularly update your operating system, Google Chrome, and all other applications. Updates often include critical security patches. You can check for Chrome updates by going to
chrome://settings/help. - Be Cautious with Downloads:
- Only download software from official websites or trusted app stores.
- Carefully read installation prompts and uncheck any bundled software you don't want.
- Use Strong Passwords: Employ unique, complex passwords for your online accounts and consider using a reputable password manager.
- Enable Safe Browsing: Ensure Chrome's Safe Browsing feature is turned on. Go to
chrome://settings/securityand select "Enhanced protection" for the highest level of security against phishing, malware, and other threats. - Review Chrome Extensions:
- Only install extensions from the Chrome Web Store.
- Regularly review your installed extensions (
chrome://extensions) and remove any you don't recognize or no longer use. Malicious extensions are a common entry point for unwanted software.
- Be Wary of Suspicious Links and Emails: Avoid clicking on unfamiliar links or opening attachments from unknown senders.
By combining Chrome's built-in cleanup tool with a robust full-system antivirus and practicing safe browsing habits, you can significantly enhance your computer's protection against malware and unwanted software.
