From the description, it seems similar to SiteAdvisor. Siteadvisor seems to rely on user information, though. Is TrendProtect similar and how accurate is it. http://www.trendsecure.com/portal/en-US/free_security_tools/trendprotect.php On occasion, SiteAdvisor will give an exclamation point to a site that's clean, and on other occasions will give a green checkmark to sites that contain some questionable downloads. I'd like to switch and get rid of the SiteAdvisor nag screen if TrendProtect is a superior BHO.
