Trendmicro is a great company providing us with yet another free tool. If you Google a site they can warn you of malware before you click. You can't always run everything through Google. This is a extension that attaches to your browser and warns you of danger as you surf.
TrendProtect adds a new button to your browser's toolbar area. The icon and color of the button changes to indicate whether the current page you are viewing is safe, dangerous, trusted, or suspicious, or whether it contains unwanted content.
TrendProtect also uses the same icon and color combination to rate the Web pages listed in your Google, MSN, and Yahoo search results. In the search results, moving your mouse over an advisory icon displays a page advisory, which has additional information about the rated Web page.
Click the TrendProtect button and select Options to customize the view, trusted pages, content categories, and connection settings. Select Check Your Computer's Security from the menu or click Scan computer for viruses in the page advisory to access free scanning and cleanup services from HouseCall.
