don't forget about npdeployJava1.dll it's either a legitimate, but not needed java deployment feature, or it's malware... either way, it's better to be safe than sorry..

Honestly, you only need to manually download the latest java plugin from sun.com for your browser version, rather than the automated stuff that you have now.. java update schedualer... it runs all the time in the background taking up resources..

here's a quote from zimbio on how to remove the Java deployment kit files..

The Java Deployment Toolkit files are located in C:\Program Files (x86)\Mozilla Firefox\plugins\npdeployJava1.dll and C:\Program Files (x86)\Java\jre6\bin\new_plugin\npdeploytk.dll. Users of 32-bit editions of Windows need to remove the (x86) part of the url so that they end up with C:\Program Files\Mozilla Firefox\plugins\npdeployJava1.dll and C:\Program Files\Java\jre6\bin\new_plugin\npdeploytk.dll.

It is now time to close the Firefox web browser and open the plugin locations in Windows Explorer. The plugins can simply be deleted in their folders which will also remove them from running as plugins in the Firefox web browser. Cautious users might want to back up the files first before they remove or delete them from the directories.
