I have tried to restore and open a corrupted file with PDF Recovery Toolbox and it was opened.
Maybe this is not the best solution for your problem but I hope it helps.

Right now the only fix would be to wipe clean the drive and reinstall.

Delivered by an email with attached .zip file where once open it rename all her text, doc and pdf files to end with .mp3 extension. you are held ransom for decryption of encrypted files. But paying does not mean they unlocked all your files.
Ie
*.pdf.mp3.
if you rename your files back to .pdf you will find the files are encrypted. It will also attach itself to network drives and rename these also. Right now the only fix would be to wipe clean the drive and reinstall.
There are 47 pages of info at bleeping computers forum. (see link below)

I would try with an "Standard" AV to see if it can recover the header, other option would be to get your hand into a tool that can let you set the PDF Version and experiment with that

I had to clean a trojan from my laptop this morning. After a few hours of work and Malware scanning, I got rid of the issue and everything seemed to be fine.
...then I realized I was wrong. I realized 'some' of my adobe files in my hard disk cannot be opened with 'File corrupt' error. I know these files are valid and usable (at least before the issue)
I realized the files that cannot be read has a PDF version 0.0 in the attributes.
The interesting thing is this issue is seen in some adobe files and not in others. I copied the supposely corrupted files into my PC, the issue is still the same on the PC - files cannot be opened.
For some files I have backups but for some I don't. So need to find a way to recover them.
Please help!
