There is a solution for this class of malware, but it isn't anti-virus. Since cryptolocker only damages user data, the operating system should provide a secure and automatic backup of the user's data. Any time a user's file is changed, the new version is recorded on the backup, with its date. From the user's point of view, the backups are read-only, so malware can't damage them, and the user can retrieve an old version of a file at any time.
I hope you are aware that this could go wrong in terrible ways: there are some files that you actually want to have only in encrypted state. If your operating system always keeps a backup of their unencrypted versions, you may be secure against certain kinds of ransomwares, but open to all kinds of other data leakage.
Actually, I'm not. I was imagining that my PC, including its secure backups, is under my control. If I take a portable computer out into the world, I don't take the backups with me; they stay in my secure location. If I modify files while I am away, there might be a way for them to be sent back home, but if there isn't the data is backed up when I return.
What am I missing?
