Google Malware Checker

A site that Google flags for malware or phishing shows visitors a full-page warning before they reach your content. The Kwebby Google Malware Checker is a google malware checker for websites: you enter a URL and it checks that address against Google Safe Browsing. The result is either "No threats detected" or "Threats detected!" with the threat types listed. This guide explains what the check covers, what it leaves out (it does not scan a phone or laptop) and what to do when a flag appears.

Key Takeaways

• The Kwebby Google Malware Checker tests one URL against the Google Safe Browsing API and reports "No threats detected" or "Threats detected!" with the threat types.
• It checks websites and links. To scan a computer or phone, use Google's help page on removing malware or unsafe software instead.
• Safe Browsing covers malware, unwanted software and social engineering such as phishing, so the tool answers a narrow question: has Google flagged this address?
• A clean result is a snapshot, not a security audit. It does not find vulnerabilities or malware that Google has not flagged yet.
• Google says reviews for malware flags take a few days, while reviews for hacked sites can take up to several weeks.
• Check your own site on a schedule and check any site before you link to it.

What Is the Kwebby Google Malware Checker?

The Kwebby Google Malware Checker is a free web tool that checks a URL against Google Safe Browsing and reports whether Google lists it as unsafe. It returns a clear verdict and, when flagged, the threat types. Use it on your own site, a link you are about to click or a site you plan to link to.

The checker is part of Kwebby's SEO tools. It tests one address at a time, so check the pages that matter most, such as your homepage and your top landing pages.

Key Features and How It Works

A Safe Browsing lookup

When you click Check, the tool sends the URL to the Google Safe Browsing Lookup API (version 4) and asks about four threat types: malware, social engineering, unwanted software and potentially harmful applications. A note under the result names Google Safe Browsing as the source. If the API call fails, the tool shows an error instead of a clean result. Safe Browsing is the same Google service behind warnings in Chrome and other products.

A plain verdict and a threat list

A safe URL shows a green "No threats detected" message. A flagged URL shows a red "Threats detected!" message followed by a list of the threat types returned, written in plain words such as "social engineering".

Any URL, including other sites

The tool accepts any address, so you can use it on competitors' links, partner sites and unfamiliar URLs from email. It does not require a login to Google or Search Console.

What Google Safe Browsing Detects

Google describes Safe Browsing as protection against three kinds of threat:

• Malware. Software designed to harm a device, the software it runs or its users.
• Unwanted software. Programs that hide harmful behavior, such as changing browser settings without consent.
• Social engineering. Deceptive pages, including phishing, that trick people into acting against their interest, for example by typing a password into a fake login form.

A page can also be hacked without being flagged yet. Hacked content is content placed on your site without your permission, and Search Console reports it separately in the Security Issues report.

Why Malware Checks Matter

Google can warn people away from a site in two places. Its help center says Google and Chrome show warnings such as "This site may harm your computer" in search results or as a full-page interstitial in the browser. Either one stops visitors before they read a word.

Hacked sites often stay infected for a while because the owner does not see the problem. Attackers sometimes show malicious content only to certain visitors, which hides it from the person who runs the site. A routine check catches a flag early, before customers report it.

How to Use the Google Malware Checker

1. Open the tool and find the input field with the example https://example.com.
2. Type or paste the full URL you want to test.
3. Click Check, or press Enter. The button reads "Checking..." while the lookup runs.
4. Read the result: a green "No threats detected" or a red "Threats detected!".
5. If the result is red, read the list of threat types under the message.
6. If you see an error message instead of a verdict, wait a moment and try again. The tool allows 15 checks per minute per visitor.

What to Do If Your Site Is Flagged

1. Confirm the problem in Search Console. Owners can open the Security Issues report to see hacked content, malware or social engineering findings.
2. Find and remove the cause. Scan site files and the database for injected code. Common entry points are outdated plugins, an old CMS and stolen FTP credentials.
3. Close the vulnerability. Update the CMS, themes and plugins, remove unused ones, change every password and review file permissions. The WordPress Theme Detector helps you see which theme a WordPress site runs so you can check it for updates.
4. Request a review. Describe what you fixed in Search Console. Google's help says malware reviews take a few days and hacked-site reviews can take up to several weeks.
5. Keep watching. Set up Search Console alerts and re-run this checker on a schedule to catch reinfection.

Best Practices for Malware Checks

Test more than the homepage

Attackers often inject code into one template or one directory. Test your homepage, a product or service page and a blog post, because a flag may attach to a single path.

Treat a clean result as one signal

"No threats detected" means Google has no flag for that address today. It says nothing about weak passwords, old plugins or a freshly injected script. Pair it with regular updates and backups.

Avoid common mistakes

• Do not use this tool to check a device. It tests URLs only.
• Do not request a review before the site is fully clean. A failed review costs time.
• Do not ignore a single flagged URL. Treat it as a sign of a wider compromise until you prove otherwise.

Common Use Cases

• Routine health checks. Test your key pages weekly or after any plugin update.
• Link vetting. Check a site before you add an outbound link or accept a guest post from it.
• Client work. Run a quick safety check on a new client's site before you start an audit.
• Email and ad links. Check a link that looks off before anyone clicks it.

Related Kwebby Tools

The Suspicious Domain Checker adds a DNS blacklist lookup of the domain's IP and a DNS test to the Safe Browsing result and scores the domain out of 3. The Blacklist Lookup checks an IP address, or the IP a domain points to, against DNS blacklists, a different type of list from Safe Browsing. The SSL Checker verifies that your HTTPS certificate is valid, which protects visitors from interception but says nothing about malware.

Final Thoughts

The Google Malware Checker answers one question quickly: has Google flagged this address as unsafe? Run it on your homepage and two or three key pages today, then schedule the same check weekly. If a page comes back red, start with the Security Issues report in Search Console and clean the site before you ask for a review. For a wider view of a suspicious site, run the Suspicious Domain Checker next.
