Here is what I find:

http://www.java.com/en/download/uninstallapplet.jsp

Reports:

There are no old versions of Java on your computer
You have the recommended version of Java installed (Version 7, Update 25)

I rerun Software updater and it reports:

Local Version: 7.0.250.16
New Version: 7.0.250.17

Someone is wrong. Is it Oracle or is it Avast Software Updater?

I have other things to do than to sort out problems like this.
