firefox 2.11

when i restarted my machine, i was promted to start java. I canceled it.
the i opened a jnlp file from a remote machine using a browser to start my application, it prompted to me to start Java. I cancelled it again. Now i get a error thrown in a small window that the "server was not found".
which is a wrong error.
This was caused by unsigned jscheduler.exe and jqsnotifier.exe.
