Internet security and malware are an ongoing worry for small businesses, and not just because they don't have access to big company IT resources (see what happened to Sony). “Safe Surf” (currently in “beta” form for Windows) is aimed at the malware problem by allowing users to connect up to a secure, inexpensive, opensource virtual desktop and use the Internet there to mitigate the worries around viruses and malware and the privacy, cost, and productivity problems they cause.
We're looking for some "early adopters" (in the sense of people who are knowledgeable about the problem, have tried various solutions, are potentially invested in finding improvements) to give the service a try and us some early feedback. See "www.e-pluribus.net" for more information.
