Malware Protection

Malware Protection shields you from dangerous websites automatically — no configuration needed.

Every site you visit is scanned in real time against McAfee SiteAdvisor's threat database. If a domain is flagged as malicious or a phishing site, the page is blocked instantly and replaced with a clear warning — before any harmful content can load. You can still choose to proceed to the site if you believe it was flagged in error.
Features:

🛡️ Real-Time Protection — Every website is scanned the moment you navigate to it. Dangerous domains are blocked before the page loads.

🔍 Search Advisor — Safety icons appear directly on Google and Bing search results, so you can see which links are safe before you click them.

⚡ Smart Caching — Scan results are remembered for the duration of your session, so previously checked sites load instantly without repeated lookups.

↩️ False Positive Override — If a safe site gets wrongly blocked, a single click lets you proceed without disabling the extension.

Privacy: Domain lookups are sent to McAfee SiteAdvisor for scanning. No personal data or browsing history is collected or stored by this extension.
