Oracle has a released an update that fixes the widely publicized security hole in their Java software. This update brings Java to version 7 Update 11 and fixes two security holes found in previous versions of the software that affected Java running in web browsers. This update also changes the default Java Security Level from Medium to High. With Java being set to High, Java will always prompt you as to whether you want to run an unsigned Java applet or a Java Web Start application.
As the security hole being patched is currently in use by various Crime Kits to exploit and access your computer it is imperative that all users install this update. To install the update, please uninstall all versions of Java by using the Windows Add or Remove Programs
or Uninstall Programs
control panel. Then install version 7 update 11 using the the following link associated with the bit-type of Windows you are using:
Windows Offline Java Installer(32-bit)
Windows Offline Java Installer (64-bit)
If you are using a 64-bit version of Windows and use both 32-bit and 64-bit web browsers, then you will need to install both versions. If you are on a 32-bit version of Windows or only use 32-bit web browsers, then you only need to install the 32-bit file.
