The malicious URL information provided through the AVG Data Feed is obtained using the same technology that powers one of the developer's other successful products – the AVG LinkScanner. The AVG LinkScanner, which is also integrated into the company's antivirus solutions, can be downloaded as a stand-alone program, and employs code analysis to determine if websites are malicious or not.
"AVG LinkScanner inspects the web page code in transit, before it displays in a browser. Using various code inspection technologies, LinkScanner reads the web code (html, javascript, vbscript etc.) and determines if the code is legitimate or malicious in real-time," explained Tony Anscombe, AVG's ambassador of free products, in a recent interview with Softpedia. "On an average day, LinkScanner detects and blocks millions of malicious URLs BEFORE users visit them," he stressed.
