It is possible that you may be dealing with a dual ransomware infection

CryptXXX, Chimera and Gomasom Ransomware appends a .crypt extension. Chimera leaves a ransom note named YOUR_FILES_ARE_ENCRYPTED.HTML. and Gomasom leaves ransom notes with names like README!!.TXT and Help_Decrypt.txt similar to CryptoWall. Based on infection rates we see, it is most likely you are dealing with a CryptXXX variant.

masterlock@india.com.crypt Ransomware will also have the .crypt extension appended to the but it uses a personal (victim) ID number followed by an email address (i.e. id-<ID>.{masterlock@india.com}.crypt} which is similar to your id<id>.{Payfornature@india.com}.crypt and leaves a ransom note named How to decrypt your files.txt.

You can submit samples of encrypted files and ransom notes to ID Ransomware for assistance with identification and confirmation. This is a service that helps identify what ransomware may have encrypted your files and then attempts to direct you to an appropriate support topic where you can seek further assistance. If ID Ransomware cannot identify the infection, you can post the case SHA1 it gives you in your next reply for Demonslay335 to manually inspect the files.

I already uploaded an example to ID Ransom 

I got resault of possible 4 diffrent ransom's: CryptXXX V.1 v.2 V.3 or Chimera.

Also Uploaded a sample to http://www.bleepingcomputer.com/submit-malware.php

When I trying to Decrypte the files with Kasparsky it's sais that the file size are not the same (I tried that with various files also with the sample pictures)

and I tired to do that with Trend Rensom Decrypter also- saiyd that the files are not similar. 

Any solution to Decrypte?

Did you also submit a copy of the ransom note to ID-Ransomware? (Along with the encrypted file)

We are drowning in information - and starving for wisdom.

Demonslay335 will most likely check out the malware submission and advise what he finds after reading this topic later today.

Is this your file that was submitted?

_Locky_recover_instructions.txt.id-E82F4E7B.{payfornature@india.com}.crypt

Looks like you may have been hit by Locky, then the "payfornature@india.com" ransomware (part of a kit that doesn't have a name yet I believe). ID Ransomware got really confused on this case, as it couldn't match either properly. The CryptXXX and Chimera were false-positives.
 
I'm curious what structure your encrypted files' names have. I see you submitted some link files, but I think Locky may have ignored those, and they got encrypted exclusively by the second ransomware. I would presume they are something like "FBC123412BCCFFAEE567091FBAC32CF5.locky.id-E82F4E7B.{payfornature@india.com}.crypt".
 
I'm afraid neither of these ransomwares have a solution. You can only backup your files and really hope for the future, since you would have to wait on the chance that both get decrypted somehow; this is a very long shot, since it is rare that one is ever cracked. Otherwise, you would need to pay both ransoms, and bank on the chances that both would actually give you a proper decrypter and key that works.
 
You should really look into the security of your computer as well; getting hit by one ransomware is bad, but two is exponentially worse. Double-check your habits and make sure your software is up to date.
 
Here is more information on both ransomwares.

I believe the unnamed one could be what is known as Bandarchor, but I haven't done enough research to properly tag that one yet.

Did a bit of research, and these ".crypt" ones don't seem to be Bandarchor, it has a slightly different pattern.

Thank you very much for the help!

We are a computer lab in israel, this a computer of a costumer. We created an image of the hard drive, wish that someday there will be a solution.

If you need more files to ceck or you have a question about what we saw and what we tried to do feel free. We would like to help fighting this ransoms.

Thank you very much for the response and help, looking for future cooperation.
