I am working on a clients computer which has been infected with Cryptolocker. Is there a way to pinpoint where and when this became infected?
I want to try moving the restore image to a new computer to see if the files can be  opened that way. I tried restoring back to before the infection, but the files are still encrypted/corrupted. Can data recovery restore these files? Is moving the image feasible?

If they got the red ransom page display then their files are already encrypted. There is no recovery other than paying the ransom.  If you disabled and removed the process before the ransom message then only the files encrypted up to that point will have been lost.

Moving the files to another machine has no advantage.

It's fairly academic about the infection entry point but you can either use the date of the active component of the win32 ransom trojan or usually the date of the infected email attachment dropper as this is almost always a socially engineered email attachment activation that launches the trojan.

Afraid a System Restore will have no effect either :(
