VirusTotal Uploader for Windows
You can make this process even easier with the free VirusTotal Uploader utility. After installing it, you can simply right-click any file under 32MB and choose VirusTotal from the Send To Windows menu. The scan results will be displayed in your browser as usual.
VTzilla for Firefox
The scanning options are embedded in Firefox's context menu and download dialog, making the analysis process as easy as clicking a single button.
VTchromizer for Chrome
Unlike VTzilla, VTchromizer does not embed itself in the browser's download dialog, only in the context menu. Google Chrome still does not offer an API to modify the download dialog, having said this, you can still scan any file that you want to download by right-clicking on the link to the file and choosing the Scan with VirusTotal option.
VTexplorer for Internet Explorer
Unlike VTzilla, VTexplorer does not embed itself in the browser's download dialog, only in the context menu. You can still scan any file that you want to download by right-clicking on the link to the file and choosing the Send URL to VirusTotal option.
VirusTotal for Android for mobile devices
Please note that VirusTotal for Android does not provide real-time protection and, so, is no substitute for any antivirus product, just a second opinion regarding your apps.
