MetaDefender Chrome Extension

The MetaDefender Chrome extension is a fast, light, and effective security browser extension that scans each in-browser download for malicious code and vulnerabilities. It processes each file or application (up to 140MB in size) you download on MetaDefender Cloud, which scans for malware with more than 40 anti-malware engines, as well as checking for vulnerabilities.

Before you run any application or open any file you've downloaded from an online source to your Mac, Android, or Windows device, scan it with MetaDefender Cloud to check for potential cyber threats, from malware to application vulnerabilities.

MetaDefender Cloud uses more than 30 anti-malware engines to check for malware, and it has a database of millions of vulnerable binaries.

To add the MetaDefender Chrome extension, click "Add to Chrome" at the bottom of this page. You'll be taken to the download page in the Chrome webstore. Click the blue "ADD TO CHROME" button.

Or, you can choose to scan each download piecemeal before you download it. To do that, just right click the file or application you want to download within your browser, and select "Scan with MetaDefender before downloading."

Once the extension goes into action, a tab will open in your Chrome browser, and the MetaDefender Cloud scanning process will begin (you may have to wait a few seconds in the queue):
