Hello there.
I have foolishly been infected by a ransomware. I managed to delete it, but sadly not before it encrypted nearly all of my files.
I am wondering if there is anyway to decrypt these files, as I can't seem to fine a decrypter for this specific ransomware anywhere online.
I believe the malware to be PClock, which is apparently a CryptoLocker copycat. 
Any help would be immensely appreciated.

Thank you for your time.

PClock ransomware does not change or append an obvious extension to the end of the encrypted data filename. There are several variants of this infection. More information and answers to frequently asked questions are provided by Fabian Wosar in this topic (Post #320). The newest variant of PClock will leave files (ransom notes) named Your files are locked !.txt.

You can submit samples of encrypted files and ransom notes to ID Ransomware for assistance with identification and confirmation. This is a service that helps identify what ransomware may have encrypted your files and then attempts to direct you to an appropriate support topic where you can seek further assistance. Uploading both encrypted files and ransom notes together provides a more positive match and helps to avoid false detections.


Fabian Wosar, Authorized Emsisoft Representative and BC Security Developer released a decryptor for some older variants of this infection. Unfortunately, newer PClock variants are not decryptable.

Fabian explains why in Post #987.

Just as a heads up: We released a blog post about the newest variants and why we are unable to help.

Note: ID Ransomware reports the infection as "Possible decryptable" only because the older variants are but it cannot tell the difference between old and new variants through the encrypted files or ransom note.

There is an ongoing discussion in this topic where you can post comments, ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.

Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. To avoid unnecessary confusion, this topic is closed.
