Thanks - no force-quit seems to come up from Safari icon, just a Quit, which doesn't do anything.
If all you saw was QUIT in the menu, you probably did not have the OPTION key held when you clicked on the option. That is, press the OPT (option) key when you click.
If you're at 10.7.2, your system is down-revision. Please run software update. Click on the Apple menu in the upper left, and select Software Update.
Beyond Java (which is not installed on Lion and later, by default), another common target for security attacks is Adobe Flash. I've removed that from most of the that systems that I deal with. Visit the Adobe web site and use their deinstaller to get rid of the Flash Player tool. (If you don't remove it, you'll find you're updating that tool fairly regularly, and OS X will automatically disable a down-revision Flash Player in recent versions, pending the update or the removal.)
