More and more users complain about the Ask.com toolbar or McAfee program's automatic installation with the JRE (if you don't uncheck it during installation). They probably downloaded the JRE from the www.java.com website.

Tip: to avoid this annoyance, you can simply download your JRE from http://www.oracle.com/technetwork/java/javase/downloads/index.html. The JRE installers don't ask for Ask.com and McAfee programs installation. In addition, to avoid their installation during an automatic update, please do not enable these famous automatic updates and simply ask for a reminder.

Second tip : to disable automatic updates (or reminder) on Windows, go to Control Panel / Programs / Java. It will launch the Java Control Panel. In the Update tab, simply uncheck the Check for Updates Automatically checkbox.
First alternative : launch the Windows msconfig tool and disable the autostart of Java(TM) Platform SE Auto Updater 2 0 (this is the jusched.exe program).
Second alternative, via CCleaner : disable the autostart of jusched.exe.
Restart your computer : auto-updates are gone.

Enjoy !
