From AVG Technologies USA:
AVG LinkScanner for Mac checks each Web page in real time before it opens on your Mac. If it sees trouble ahead, it stops you. It's quick and easy to install and won't get in your way. If the page is infected, it stops you from opening it. (This happens so quickly that you don't even notice it). AVG LinkScanner works in real time and checks for active threats before you land on a page. Search-Shield scans search results and places a safety rating next to each link so you know where it's safe to click. This applies when searching with Google, Yahoo! or Bing. AVG LinkScanner runs silently in the background--you won't even notice it until a threat is detected. Minimal use of system resources so it won't slow down your Mac.
