There was a zero-day exploit for java that was released recently. I'd look into that, and disable java if you haven't done so already.
If it's bricked, then I'd just wipe and reinstall.
"Of all tyrannies, a tyranny exercised for the good of its victims may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end, for they do so with the approval of their own conscience." -- C. S. Lewis
