What is VT4Browsers?
VT4Browsers is a Firefox extension that enables users to scan their downloads using VirusTotal's free service before storing them on their system. By checking files or links with VirusTotal, users can avoid infections and other undesired outcomes from suspicious items. The extension also allows users to share their DNS resolutions with the security industry for collective safety, with the assurance of never being tied to their identity. Note: VT4Browsers is not an alternative to antivirus or security products, but a valuable addition for a second opinion.
