Seven different color coded ratings are used in the browser plugin. Most important ratings are green for a safe website, red for a dangerous website and yellow which indicates undesirable and suspicious contents.

The second indicator becomes only visible on the supported search engine results pages. Every url on these pages, even the advertisements, will be rated by TrendProtect to give the user an indication of the possible dangers on these websites.

The ratings of the service are calculated by taking page and site reputation, phishing scam detection and content categories into account. It is possible to influence some values in the options of the plugin. This includes selecting categories like gambling or adult as undesirable. Another option is the addition of websites to a list of trusted websites.

TrendProtect is available for Internet Explorer 6, Internet Explorer 7 and Internet Explorer 8 (although it is not mentioned on the page) only at this moment. TrendMicro has plans to port the plugin to the Mozilla Firefox web browser.
