Hello,
I completely agree with Mick's comment above.
In case of SAV for Linux, check these Articles:

Secondly, SEP for Mac needs Java in order to run LiveUpdate and keep up-to-date. This is crucial as there are new threats being discovered very often which can affect Mac and other platforms.
Apple's Java support page directs users of Lion (OS X 10.7.5) and Mountain Lion (OS X 10.8.2 or later) to go to http://www.java.com/en/download/index.jsp (which is Oracle's page) to obtain Java 7 as a new installation. In other words, I don't think there is any such thing as "Apple Java" any longer, for Lion or Mountain Lion.
If you're using Snow Leopard, I don't believe you can install anything but the Java provided through Software Update.
