Looking on the bright side....
Cryptolocker has persuaded me and family members to reconsider our backup and security arrangements - on line and off line backups including versioning, properly set up firewalls, all day to day use by user accounts not administrator, education for the inexpert users, replacement or removal of as much as possible of the avoidable cr@pware (Adobe, Realplayer, Java), in addition to the existing anti-malware solutions). And then system imaging from clean installs in case the worst does happen.
All of which I should have done before. But in the belief that theat was just messing up my system and hijacking the PC for sending spam or DDoS, which can be resolved by a reinstall, it just wasn't a priority. So in some respects thank you Cryptolocker crims, you forced me to do things properly.
