A "disease vector" is a Web site or URL known to distribute Internet threats including
               spyware, password-cracking applications, key-stroke trackers, virus kit downloads,
               and other malware.
            Another category of disease vectors are sites made to look legitimate, but below the
               surface the hacker directs all the "back-end" functionality—links, data posts, and
               so on, to his or her own locations.
            Trend Micro quickly adds confirmed malicious sites to the phish and spyware pattern
               file so you can prevent LAN clients from downloading the malware, or from being duped
               by the look alike sites.
