Download Virus Checker is a free Chrome extension to check a link for viruses via VirusTotal while downloading. This extension uses the API of VirusTotal. When you try to download a file, it sends the download link to VirusTotal where the file is analyzed by up to 68 antivirus products. If the file is harmful, a warning window is opened in which you can see the report of that file. After that, you can cancel the download progress (possible when file size is large and not downloaded yet) or delete the file from your PC. This extension can’t prevent downloading but can alert you about the threat.
You can also adjust a couple of options of this extension. You can set the number of positive reports/viruses to display the warning and also add File Types (audio, video, text, etc.) to the whitelist. After that, the warning window will open as per the options set by you. If no virus is detected for a file, it won’t display any window.
Above you can see the warning window for a file. The VirusTotal link is also added in that window so that you can directly view the report on VirusTotal.
Note: While testing the software, the whitelist option didn’t work for me. This option is used to skip the scan for whitelisted items, but it failed to work.

We have also covered some antivirus link checker extensions for Google Chrome.
Normally, we first download a file and then upload it to VirusTotal. Or else, we first copy the file link, open VirusTotal in a new tab, paste the URL, and then view the generated report. But using this extension is better than manually checking the VirusTotal report for a file. What I didn’t like is it doesn’t stop downloading for a harmful file. Still, the extension is good to check the VirusTotal report and then decide whether you should keep the file or not.
