What is it? Based on the picture I'd say that is disk corruption. Either it's just the file system, or the flash drive itself is broken. Where did it come from? Disk corruption can happen for many reasons. Perhaps you pulled out the drive while it was writing (didn't "Safely Eject" it), or the drive just took too many physical bumps, or ...

It all depends on how the antivirus software works. 32-bit programs might not be able to interoperate directly with running 64-bit processes (other than through the Windows API), but they do still have access to the entire file system including files containing 64-bit code.

I've got bad news for you - the files are lost, unless you've got a backup. Cryptolocker uses proper crypto combination (RSA-2048 and AES), and it's done right, so you've got very little chance of recovering anything.
