From over 400,000 detected applications, the Software Inspector tagged over 35% as insecure versions!

For IE 6.x users, 4.12% were insecure, which is a good sign; most people probably are aware of using Windows updates to get new IE versions.

For Adobe Flash 9.x users, over 53% were running insecure versions; a testament to both the popularity of Flash-based web content, and the lack of awareness on Flash vulnerabilities.

More than one third of Firefox 1.x users (35.47%) were found to be running vulnerable versions; while Opera users were safer, with only 13.04% running vulnerable versions of Opera 9x.

Only 6.8% users were found to run insecure versions of Skype 2.x, the popular VoIP program.
