Translate sello antivirus from Spanish to English

– A mechanism that helps reduce the volume of antivirus scanning that is required across an organization by stamping messages that have been scanned for viruses with metadata that indicates the version of the antivirus software that performed the scan and the result of that scan. This metadata, or "stamp," travels securely with the message as it is routed through different e-mail servers within the organization and is used to determine whether subsequent additional virus scanning on the message can be bypassed. ¹
