So my wife's new computer got hit by the Cryptolocker ransomware. I guess I forgot to install antivirus and I think she got it from a sketchy email on her work account; although she says she didn't click on any links/attachments. After some previous issues with data backups and losing things, I convinced her to use Dropbox to backup all her files. Unfortunately, since Cryptolocker encrypts all documents with specific extensions, Dropbox just backed up all the encrypted files.
I found a help document that said to send their support staff a link to the event in case you need to undo said event and I've done so. I'm hoping Dropbox can undo it in a batch, otherwise it looks like you have to select each file and revert to the older version, which is a multistep process. And of course my wife has all her academic and teaching materials on there, which accounts for over 3000 docs.
So a) whoever made this is an a$$hole and b) be careful about using automatic cloud storage with this new breed of dickishness out there. Does anyone know if I need to wipe the computer and reinstall, or can I just remove Cryptolocker and the encrypted files and carry on? Anyone have any recommendations for a periodic, easy backup system for a laptop that would not be susceptible to this sort of attack?
