Avira Browser Safety is a free extension that blocks malicious and phishing sites, ads and trackers, and cross-checks search results with its URL cloud. PhishClean adds local checks for suspicious forms, hidden elements and leaked credentials.

| Capability | PhishClean | Avira Browser Safety |
| --- | --- | --- |
| Search and destination reputation | Yes | Yes |
| On-page phishing behavior analysis | Yes | Partly: Avira says it scans page source for malware and trackers |
| Exposed secrets and JWT leak detection | Yes | Not listed |
| HTTPS downgrade and iframe heuristics | Yes | Not listed |
| What the vendor says it handles | Nothing about the pages you visit is sent to PhishClean | Chrome listing: location, web history and website content |

Avira details are from its product page and [Chrome Web Store listing](https://chromewebstore.google.com/detail/avira-browser-safety/flliilndjeohchalpbbcdekjklbdgfkk), checked November 2026. "Not listed" means we didn't find it there, not that Avira can't do it. Features change, so check there before relying on a row.

If you mainly want reputation help in search results or on known domains, Avira Browser Safety can be enough. If you want the browser to inspect the page itself for phishing mechanics and exposed credentials, PhishClean covers a different layer of risk.

## The core difference: what each one does

Avira combines a cloud check on addresses with a scan of the page's source code.

### What Avira Browser Safety says it does

Avira says it scans a page's source code for malware and trackers, and that each search is cross-checked with the Avira URL Cloud before you click a result. It also blocks ads and trackers and flags unwanted downloads. Its Chrome listing names location, web history and website content among the data it handles, and its Firefox listing says URLs are processed in anonymized form.

### 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](https://www.phishclean.com/transparency), good or bad.

## Where Avira Browser Safety is stronger

- Search results cross-checked with the Avira URL Cloud before you click
- Ad and tracker blocking in the same free extension
- Flags potentially unwanted applications bundled into downloads
- Works in Opera as well as Chrome, Firefox and Edge

## 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 Avira Browser Safety 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 the sites you visit kept off the vendor's servers
- Want to see *why* a page was flagged, signal by signal

### Avira Browser Safety fits better if you:

- Want ads and trackers blocked by the same free extension
- Want warnings about unwanted downloads
- Already use Avira 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. Avira adds ad and tracker blocking and download warnings, and PhishClean adds local checks for forms, hidden iframes and leaked tokens. If you only want one extension, choose by what you need most: a free extension that also blocks ads, 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.
