PhishClean vs McAfee WebAdvisor

McAfee WebAdvisor warns about sites known for phishing and malicious activity, scans downloads and catches mistyped addresses. PhishClean focuses on what appears and behaves on the page after it loads.

McAfee details are from its WebAdvisor page and blog, checked November 2026. "Not listed" means we didn't find it there, not that McAfee can't do it. Features change, so check there before relying on a row.

WebAdvisor can help users avoid known-bad links and downloads. PhishClean is more useful when the risk is inside the page itself: a fake login flow, a hidden iframe, a downgraded HTTPS session, or exposed credentials in the source.

The core difference: what each one does

WebAdvisor's strength is breadth around the page: it warns about bad destinations, scans downloads and catches mistyped addresses.

What WebAdvisor says it does

McAfee says tools such as WebAdvisor check addresses against continuously updated databases of known malicious sites, and that it blocks malware and phishing sites if you click a bad link by accident. It also scans downloads and protects you when you mistype an address. McAfee's AI Scam Detector is a separate product. We didn't find a clear statement of what WebAdvisor sends to McAfee when it checks a site, so we make no claim about it.

What PhishClean does

PhishClean reads the page in front of you and runs 27 detection signals in the browser: login forms that post to a different origin than the one shown, hidden and off-screen iframes, homograph and lookalike domains, HTTPS silently downgraded to HTTP, and API keys, JWTs or session tokens exposed in the page source. It also matches each site against a list of about 380,000 reported phishing sites on the device. The page checks do not need anyone to have reported the site, but they can only flag a page that shows one of these signs, so a convincing page that shows none of them gets through. We publish our test results, good or bad.

Where McAfee WebAdvisor is stronger

• Blocks malware and phishing sites when you click a bad link by accident
• Download scanning, which PhishClean does in a more limited way, warning on disguised and risky files
• Typo protection when you mistype an address
• Familiar to anyone already running McAfee on the desktop

Where PhishClean is stronger

• Page checks that do not need a site to have been reported first, and that run on your device
• Secret and token leakage — exposed API keys, JWTs and session tokens on the page, which WebAdvisor does not list
• Hidden iframes and form-action mismatches used for clickjacking and credential capture
• HTTPS downgrades and SSL stripping on connections that look fine in the address bar
• Privacy: no URL and no page content is sent to us, because every check runs on your device

Which should you choose?

PhishClean fits better if you:

• Want page checks that run on your device
• Handle credentials, API keys or tokens in the browser
• Want a published list of every network request, so you can check what is sent
• Want to see why a page was flagged, signal by signal

McAfee WebAdvisor fits better if you:

• Want downloads scanned by the same extension
• Want typo protection for mistyped addresses
• Already use McAfee and prefer one vendor for the whole machine

Can you run both?

Yes. We know of no conflict, though we have not tested every version together. WebAdvisor adds download scanning and typo protection, and PhishClean adds local checks for forms, hidden iframes and leaked tokens. If you only want one extension, choose by what you need most: download and typo protection from a large vendor, or local page checks with a paid plan for the full set.

Frequently asked questions

Does PhishClean send my browsing history anywhere?

No. Every one of the 27 detection signals runs inside your browser, and no URL, page content or form data is sent to PhishClean. Two paid checks contact other services: the leaked-password check sends the first 5 characters of a password hash to Have I Been Pwned, and the coding-test repo check asks GitHub, GitLab or Bitbucket about the repository you opened.

Is PhishClean free?

Five detection signals are free permanently, including blocking of reported phishing sites. The full set of 27, along with findings detail and history, is $9/month or $59/year. New installs start with a full-featured trial.

Will running both extensions slow my browser down?

We have not seen a slowdown, but we have not published a benchmark. PhishClean's page checks run in your browser when a page loads, so the page does not wait on a server for them. We have not measured the other extension's speed.
