Qualys's BrowserCheck results for Adobe Acrobat + Reader may not be entirely accurate. I have both Acrobat 8 and Reader 9 on my PC, both fully patched. According to Firefox it is using the plugin from Reader 9 and there is no plugin from my install of Acrobat 8. Something is wrong with their detection mechanism because BrowserCheck says I am using an out of date Reader 8 plugin that needs patched.
Well it did when I tried the service 6 months ago, haven't checked if they've fixed it since.
