How to configure Metadefender Chrome Extension

  1. Download and install the extension from the Chrome online store.
  2. After installation, you will be redirected to a web page. Do not close this tab and let it load completely.
  3. Check the API key and confirm it by clicking the metadefender icon next to the address bar.

Once downloaded and installed, each download is now checked for vulnerabilities. You can disable auto scan and switch to manual mode. In manual mode, right-click on a download link and select’Scan file before downloading’. Manually scanned files are not automatically saved in the Downloads folder. You must download them separately after scanning.

The extension provides your downloads through a variety of online anti-malware services. Some of them are ESET, F-Secure, Microsoft, McAfee, Sophos, QuickHeal, Symantec and TrendMicro. There are a total of 41 anti-malware services that scan your downloads. And the result for each service is displayed with it.

Other details such as PE information, application list, network connections, etc. are also displayed.

If a file is classified as vulnerable or malicious, its value of 41 is given. So many anti-malware services mark the file as malicious. For testing purposes only, I tried to download a test virus and was immediately notified by the program. The file was reported as malicious by 39 of the 41 services.

The entire downloading, downloading and scanning process increases the total file download time. But if you’re a security monster, it can be perfectly normal and worth it.

Downloading unsecured files from the Internet is one of the main causes of virus problems.
