I downloaded the trial version of LinkScanner Pro. It works with Internet Explorer 7 and Mozilla Firefox 18.104.22.168 to keep your surfing safe. It will block exploits and web sites with any exploits. You can test if it works. Before clicking any website links, you can check them with Quick Scan when you right click. It can also filter Web search results with Google, Yahoo or MSN. This is similar to McAfee SiteAdvisor but I prefer SiteAdvisor because as you browse, a small button on your browser toolbar changes color as shown. LinkScanner Pro does not show any color coding on browser toolbar.
The differences between the Pro and lite versions are the Pro version will block threats your firewall lets in, secure vulnerable Web-connected applications, automatic real-time site risk analysis, always-on exploit blocking, automatic expanded threat detection and alert reporting and logging.
