I found a helpful extension for my web browser (Safari) called WOT which scans links and alerts you when you are about to visit a bad website. It uses a system which allows other users that use the same extension to place ratings on the websites so you can know which websites to trust and which ones not to trust, This extension works on all major web browsers and is free to use.
