A big FBI/DoJ takedown resulted in a whole wackload of servers of the (nasty) Crytolocker virus recently. YAY. But, it's down but not out; other servers are still out there.

I'm working on some new features for Constant Care and Weekly Care w/AV subscribers, the first of which will block the Cryptolocker virus from infecting.
Another will attempt to block the accidental installation of toolbars and junkware ("PC Optimizers", etc).

A third will do a regular uninstall of any recognized junkware that does manage to slip by.
