Unfortunately, malware has a bright future. The maturation of "Web 2.0" applications and services - with more software functionality pushed onto client systems and browsers - adds new vulnerabilities. Client systems are less protected than servers, making the larger footprint of Web 2.0 applications an inviting target. In addition, the tremendous profit potential of cyber crime has raised skill levels and created an entire criminal service industry devoted to stealing information or making money from stolen machines. Malware developers now write exploits rivaling commercial software in sophistication and quality, and their exploits are far more difficult to detect and clean.
Malware threats are fueling rapid growth in the worldwide market for defenses, with estimates ranging as high as 99% of networked systems used in business having some form of anti-malware defense installed. The annual growth rate for anti-virus software and services is forecasted to grow at 10.9% yearly from 2006-2013, climbing from $4.7 billion to $9.7 billion in annual global sales (Frost & Sullivan 2007, Worldwide Anti-Malware Products Market).
