Hey Nihil, it's been a while. I had considered opening the file in a hex editor or notepad and checking for similarities that may just corrupt the file instead of encrypt it but it looks like this is related to a Vundo variant. Malwarebytes removed the infection when I first accessed the machine and I was hoping that would help unlock the files but it didn't. Panda and Kaspersky have decryptors for a different algorithm created by the Rannoh trojan. I tried this just in case but it didn't work. These follow the format of "Locked-filename.ext.xxxx". Mine however was "filename.ext.html". There are 2 decryptors I found for Vundo, FileUnlocker and FixXrupter, but these can't fix the problem. Know of any other decryptors?
