Security firm VeriSign has released the "VeriSign Trusted" website authentication service.
The service will verify to the user that the website actually represents who it says it represents.
VeriSign Trusted will also scan a website for malware and warn users before they enter an infected website.
The tool will also verify that the website is using network encryption protocol that secures the communication between users and the website.
The company's vice president for product marketing, Tim Callan, explained that the new tool, combined with VeriSign SSL, will perform routine scans of website to check for malware.
In a statement, he said: “Our seal and our service is widely understood to be the most recognized, most prominent indicator of a safe Web experience.”
The company also announced that it would be adding its authentication seal to search results on shopping search engines such as Pricegrabber and TheFind.
People using AVG's LinkScanner tool will also see the seal on Google and Bing search engines.
