I have had some minor issues with Java updates and generally it has to do the upgrade process. So now what I generally do is if a Java update is announced or flagged I will go to the Control Panel and completely uninstall Java from my computer. You can also delete the Sun directory manually in %AppData% or:
C:\Users\xxxxx\AppData\LocalLow\Sun\
Then I will download the non-spam-ware version of Java instead of one at java.com.
This is found here on the Oracle website:

You click to accept the Agreement then pick the Windows x86 Offline installer. Seems to work a lot better and doesn't try to install ad-ware.
