What is a website malware scanner?
The Website Malware Scanner checks any URL against known malware databases, Google Safe Browsing lists, and spam blacklists to determine if a site has been flagged for malicious activity, phishing, or malware distribution. It provides a quick security assessment for any website.
A hacked or malware-infected website can be catastrophically penalised by Google — removed from search results entirely until the infection is cleaned. Google's Safe Browsing service flags millions of unsafe sites monthly. Knowing your site's security status, or the status of sites you're considering linking to, is essential for maintaining your SEO reputation.
Why use a website malware scanner?
A compromised website that serves malware or participates in phishing can be blacklisted by Google, removing it entirely from search results. Recovery from a Google blacklist is time-consuming and damaging. Regular security scans catch problems early, before they become indexation emergencies.
Google's Safe Browsing service automatically detects and blacklists sites serving malware, hosting phishing pages, or engaging in deceptive practices. Blacklisted sites show a red warning page in Chrome before users can visit.
How does malware affect SEO?
Google immediately removes blacklisted sites from search results. Even after cleaning malware, sites remain blacklisted until manually reviewed by Google, causing extended periods of zero organic search traffic.
How do sites get hacked?
Common attack vectors include outdated CMS plugins, weak passwords, vulnerable server software, SQL injection, brute force attacks, and compromised FTP credentials. Keeping software updated is the most effective prevention.
What should I do if my site is blacklisted?
Identify and remove the malware (your host can help), update all software, change all passwords, then submit a review request through Google Search Console's Security Issues report explaining what was fixed.
How often should I scan my site for malware?
Scan weekly for active sites. Set up automated monitoring where possible. Always scan immediately if you notice traffic drops, receive user complaints, or make changes to server configurations.
