AVG Link Scanner is a new security component that includes Search-Shield and Active Surf-Shield functionality inside AVG 8.5 Free Edition to protect users against random, invisible online threats. It provides you real-time protection while you surf or chat online scanning the pages behind all the links you click or type into your browser.

Search-Shield scans search results and places a safety rating next to each link, so you know where it’s safe to click. Active Surf-Shield scans the page behind any link you click on or any web address you type into your browser. If the page is poisoned, it stops you from opening it.

• It doesn’t rely solely on a blacklist of bad sites that can quickly go out of date.

• It doesn’t rely on opinion – it looks at what’s really on the web page.
• It’s quick and easy to install.
• It works unobtrusively in the background and doesn’t slow your PC down.
• It works smoothly alongside other major brands of security software.
• It’s free, forever.
