Quoted from vid1900:I just tried it and it did not install a virus - BUT I do not have Java installed.
NEVER install Java on your computer, and always disable it if you somehow have it.
Here's a simple solution that I use:
I have Firefox installed with "NoScript" plug-in. It only runs javascript on sites that I OK.
So, Pinside is OK'd, but google-analytics.com is NOT (which pinside uses).
That also means if I go to a new website, the javascript is off by default, until I OK it.
