The Hidden Security Guard in Your Browser
When most people think of antivirus software, they picture dedicated desktop applications running heavily in the background. However, because the web browser is the primary gateway for malware, phishing attempts, and data theft, Google has built a surprisingly robust security suite directly into Chrome.
This built-in tool is called Safety Check. It does not replace a full-system antivirus (like Windows Defender), but it acts as a critical first line of defence. It scans your browser for compromised passwords, malicious extensions, outdated software, and harmful website permissions.
How to Run a Manual Safety Check
Google Chrome will occasionally run safety checks automatically in the background, but if you suspect your browser is behaving strangely—perhaps showing unexpected pop-ups or redirecting your searches—you should run a manual scan immediately.
- Open the Google Chrome browser on your computer.
- Click the three-dot menu icon in the top-right corner of the window.
- Select Settings from the dropdown menu.
- In the left-hand sidebar, click on Privacy and security.
- Look for the section titled Safety Check near the top of the page.
- Click the blue Check now button.
Chrome will take a few seconds to scan your profile and display a checklist of results.
Understanding the Safety Check Results
Once the scan is complete, Chrome will provide a status report on four critical security areas. Here is what you need to look for and how to resolve any issues found:
1. Updates
Hackers constantly exploit vulnerabilities in older versions of web browsers. This section confirms whether you are running the absolute latest, patched version of Chrome. If there is an update pending, Chrome will prompt you to Relaunch the browser to apply it.
2. Passwords
This is arguably the most valuable feature. Chrome cross-references every password you have saved in its autofill manager against a massive, encrypted database of known data breaches on the dark web.
If Chrome finds a match, it will alert you that a specific password has been compromised. You should click the Review button immediately. Chrome will list the exact websites where your password was exposed and provide direct links to those sites so you can change your passwords before a hacker logs into your accounts.
3. Safe Browsing
Safe Browsing is Google’s technology that blocks you from visiting known phishing sites or downloading malicious files. This check ensures the feature is turned on. For maximum protection, you can click into this section and upgrade from "Standard protection" to "Enhanced protection." Enhanced protection proactively sends URLs and small samples of downloads to Google’s servers for real-time analysis before they reach your computer.
4. Extensions
Browser extensions are a major vector for malware. You might install a safe extension today, but a year later, the developer might sell it to a malicious company that silently updates it to track your keystrokes.
The Safety Check scans all your installed extensions and will flag any that have been recently removed from the Chrome Web Store for violating security policies. If an extension is flagged here, click Review and remove it from your browser immediately.
By making the Chrome Safety Check a regular part of your digital hygiene routine, you can catch compromised passwords and malicious extensions long before they cause serious damage to your digital life.
