Is there any way to decrypt files encrypted by Ransomware

I have been searching for some techniques which can be used to decrypt Ransomware affected files.

There are some ways like System Restore which actually doesn't work.

Can anyone have some good knowledge about how can we do it.

While I have knowledge about this.

The thing here is what you use for Ugo Ransomeware won't work for Hilcrop infections. This means you have to identify the infection by name first. If you can't then you turn to a wipe of the machine and restore from recovery media and backups.

-> We are now decades into PC use. All owners today know about backups. Whether they do or not seems to be if they value what's on that PC.

PS. Added this with edit. I forgot my goto forum when I can't ID the culprit is Bleepingcomputer.com. I don't go there often but when I do, it's serious. Great place.

Is that the answer to my Question?

Hi R. Proffitt,

I think that your reply was not the one I am looking for. I simply asked you that is there any way to decrypt files by Ransomware or Locky or Crypto..

You are asking for something that doesn't exist yet. You want to decrypt for 3 or more ransomware systems. And in those 3 there are often variants so I'm back to the beginning. You have to identify the pest/ransome first then research how to decrypt.

If you can't do this identification or decryption I'd still get to bleepingcomputer forums.

"I think that your reply was not the one I am looking for. I simply asked you that is there any way to decrypt files by Ransomware or Locky or Crypto."

I have to write no. Each ransomer uses a different encryption plus there were versions that could result in losses. You just know what you are dealing with before you attempt a decryption.

I'm going with my first advice and write you need to ID the culprit first. Bleepingcomputer is great for this.

That said, I am seeing folk that want one stop decryption. I haven't seen that yet.

None That I Know Of, Except To...

....wipe the drive, reinstall the operating system, drivers, and programs, then replace all important documents and files using your backups. If you happen to have a backup system image, then the reinstall is quicker and easier but so far, I know of no way to actually decrypt the infected files while in place. Of course, there have been a few who paid the ransom and got relief when the malware writer gave them the decryption key, but even paying the ransom doesn't guarantee a "good" key.

Hope this helps.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
