i am not being able to recover .coot virus infected photo when i recover it still is corrupted .plz help me or give me solution..plz reply back
Recuva will not 'decrypt' files following a ransomware attack, it is not meant to do that and cannot do that.
Recuva is used to recover files that you have deleted (by mistake).
Your files have not been deleted or corrupted, they have been encrypted by the ransomware.
Forum rules mean that we cannot directly help with malware removal here, but can point you to where you can get help.
I suggest that you go to : https://forums.malwarebytes.com/forum/7-windows-malware-removal-help-support/
and read the topic "I'm infected - What do I do now?":<a href="http://%20https://forums.malwarebytes.com/topic/9573-im-infected-what-do-i-do-now/" rel="external nofollow"> https://forums.malwarebytes.com/topic/9573-im-infected-what-do-i-do-now/</a>
Follow the instructions there to get one-to-one help cleaning up your computer.
Other malware removal help websites are available and can be found in part 10 of our forum rules.
https://forum.piriform.com/announcement/15-forum-rules/
Any one of those sites will help you clear all remnants of any malware/virus from your machine.
They should also be able to advise if there is any chance of decrypting the files.
However following a ransomware attack unless you have a backup of the files then they are probably lost to you.
I suggest you go here, it's dedicated to ransomware.
