If you use Internet Explorer, Firefox, Chrome, Safari or Opera, check out Web of Trust. What it does is protect you from visiting websites, when performing searches, that may be harmful by using a visual “traffic light simulated” alert system. If you see red (potential danger lurks ahead), if you see yellow (use caution) and green (go for it). In other words, it is a visual rating system that is engineered to heighten your awareness of what sites are good and what sites could be bad. WOT shows the reputation of a website in terms of four components: Trustworthiness, Vendor reliability, Privacy, Child safety.
Best of all, it’s a free download/web app. Very cool!
