The ZILLAbar's advanced Phishing protection uses multiple technologies to help detect known and potential Phishing sites.
The addresses (URLs) of the latest known Phishing sites are downloaded from multiple databases many times each day, and included in your ZILLAbar updates.
In addition, the ZILLAbar uses heuristics -analysis of behavior and content- to determine the likelihood that a particular site is UNSAFE. Its unique Anti-Phishing Scoring Engine subjects the Web content in your browser to a set of sequential evaluations intended to identify fraudulent sites. When the score reaches the threshold level, the ZILLAbar displays a warning indicating that the site you are attempting to visit is a potential Phishing site. You can still access the site, but you are advised not to do so.
