In other words, Web 2.0 as a platform is in danger. "Considering that there are highly ineffective viruses for Mac and Linux platforms, I'm going to be leaning more with the likelihood that tomorrow's threats on non-Windows platforms are going to take place in the Ajax filled wonders of the World Wide Web. Why? So you can develop a single malware script and execute on all three platforms, assuming it's cross platform, of course."
