A collaborative initiative to combat viruses, spyware and other malware, it is based at Harvard University's Berkman Center for Internet & Society and is funded by Google, PayPal, Mozilla, AOL and Trend Micro.
It collects the URLs of the websites, whether they are malicious or compromised, and uses the information to support and encourage site owners and web hosting companies in cleaning up and protecting their sites.
It also conducts analysis of infection trends, offers independent reviews of its partners' findings, and operates a community website - BadwareBusters.org - that provides help to people who have been victims or who wish to avoid becoming victims.
Sunbelt Software's director of malware research, Eric Howes, has been an advisor to StopBadware.org since early in its development, but the data partnership represents the first time the company has established an official relationship with the project.
The company will provide research data via ThreatTrack, which collects data from multiple sources including research from Sunbelt Labs, ThreatNet and Sunbelt's VIPRE user community.
Howes said: “Sunbelt Software has always encouraged a collaborative approach to addressing the malware problem. We are pleased to formalise our ongoing relationship with StopBadware.org and support the important work it does in educating the public and the industry.”
Maxim Weinstein, manager of StopBadware.org, said: “We are thrilled that a well-respected anti-malware company like Sunbelt Software has come on board as a data partner. The new data offers us a different view of the badware website landscape and will help us to extend our reach and to provide richer analysis.”
