Antivirus software revenue is expected to total $4.9 billion in 2007, and will account for 53.8 percent of the total security software industry.

All vendors in the enterprise antivirus market are working on road maps for converged clients (not necessarily a single product or even a single install, but products that can be managed together and are one stock-keeping units) with anti-spyware, personal firewalls, intrusion prevention system (IPS) software, and policy enforcement (aka network access control).

• Gartner forecasts that for the next 18 months, less than 15% of enterprise clients will purchase licenses for converged clients for their entire desktop population. 
• Enterprise adoption of converged clients will slowly increase, and by year-end 2009, 35% of enterprises will have purchased deployed converged clients.
