I'm running a pc with windows 7. a few years ago, my files were encrypted by ransomware with a .abc extension. At the time, there was no solution. I recently heard about tesladecoder from your site, and downloaded it. Despite running it as instructed on the page below, my files are still encrypted.
The program says decryption finished. 0 files decrypted, 0 skipped, 0 warnings. Thanks for any help!
