Hi Folks:
All my hard drive files have been corrupted by ukash ransomware.
Story so far-
After the initial attack I used AVG anti virus and Superanti spyware but not in safe mode. PC was then able to function but all files on hard drive had been corrupted. I contacted a PC advisor who was unable to fix and replaced the hard drive with a new one and is currently looking for solution with the old drive which contains all my old corrupted files but no joy to date.
Any help would be appreciated.
Regards

Hi and welcome to MalwareTips! :)

I'n Fiery and I would gladly assist you in removing the malware on your computer.

Before we start:
  • Note that the removal process is not immediate. Depending on the severity of your infection, it could take a long time.
  • Malware removal can be dangerous. I cannot guarantee the safety of your system as malware can be unpredictable. It is possible that we might encounter situations where the only recourse is to re-format and re-install your operating system. Therefore, I would advise you to backup all your important files before we start.
  • Please be patient and stay with me until I give you the green lights and inform you that your PC is clean.
  • Some tools may be flagged by your antivirus as harmful. Rest assure that ALL the tools we use are safe, the detections are false positives.
  • The absence of symptoms does not mean your PC is fully disinfected.
  • If you are unclear about the instructions, please stop and ask. Following the steps in the order that I post them in is vital.
  • Lastly, if you have requested help on other sites, that will delay and hinder the removal process. Please only stick to one site.

Hi Fiery: Thanks for prompt reply. However just to clarify- my corrupted hard drive has been removed from my pc which has now been setup with a new hard drive and functions fine.
My old hard drive is with a pc advisor and as all my personal files have been corrupted and have been replaced by a mass of random symbols, there are no files to save.
What Im hoping to do is recover these files by removing the corruption.So the starting point is for my PC advisor to install my corrupted drive on one of his pcs. Then do I proceed with your instructions as stated ?

Thanks very much for your offer of help.
Regards

Thanks

Hi,

That's unfortunate. It sounds to me your drive was crippled by a file encrypter. Depending on which variant you are infected by, there may or may not be a chance to retrieve your files.

If your PC advisor can't come up with a solution, take the drive back and I'll give it a try after you follow the instructions above on the corrupted disk. It would be helpful if you ask if he knows what the infection name is.
