This has nothing to do with Mac except that Mac anti-virus vendors are spinning it that way to boost sales.

It is a problem if you have a Java plugin installed and you run an unsigned Java applet from a fake video site, AND you are using an old version of Java.

According to the discussion on the Ubuntu forums, it does not install anything permanently (on Linux anyway). I do not have Java installed at all and if I did it would be kept up to date by the package manager.

@frontpage, it says households, not users. I use Linux, if my wife choose to run Windows on her PC that would not mean that I needed Windows, but it would mean our household had both. In fact, I run XP in a virtualbox VM just to run IE6 for testing.
