I have tried multiple online available ransom decrypters but they don't seem to be working, can you please guide which tool can assist me?
 
I have attached the encrypted files snapshot with this post.

 

These are database files and only these are encrypted, rest of the application is working fine.

We need more information. You have not attached anything (nor does this forum let you do so). Have you had the ransomware identified on ID Ransomware by uploading an encrypted file and ransom note? I've not heard of "Imme" for a ransomware. Do your files have an extension added, and do you have a ransom note.

 

Please follow the directions here when posting for help: https://www.bleepingcomputer.com/forums/t/608844/how-to-post-a-topic-asking-for-help-with-ransomware/

Ah, I do have that extension listed as Xorist. Several other victims have uploaded the same note and extension before. You'll need an encrypted file and it's original, and use them with the Emsisoft Xorist decrypter. If that doesn't work, you'll need to share with us the file pair you are using.

Please read these quotes from Fabian Wosar that have been repeated multiple times. You can almost always find a clean copy of something that was encrypted. It just needs to be a single file pair of an encrypted and original file.
 

Even you will have at least one file where you can get the original version of the file of. A picture you shared with your family. The default wallpapers shipped with your version of Windows. A file you downloaded from the internet that you can download again.
 
In the years I have been doing this, there hasn't been a single case where decryption failed because someone could not possibly find at least one file where they could somehow find the original file as well.

 

It has to be the original. I don't believe you that there is no file on your system where you can't get the original of. Examples: Files you downloaded from the internet that were encrypted, that you can simply download again to get the original, pictures that you shared with friends that they can just send you back, default wallpapers and pictures that were included with your Windows version that you can just get from another system running the same Windows version. There are plenty of ways to get an encrypted with unencrypted file pair.

@Malick
 
Can you find some encrypted doc or docx files and upload them onto https://sendspace.com?
