[My PC has been attacked by Ransom.Cryptowall 3 and adds this content .id[F0CAE4F1-2241].[backup3389@cock.li].adage]

My PC has been attacked by a ransomware known Ransom.Cryptowall 3 that adds this ".id[F0CAE4F1-2241].[backup3389@cock.li].adage" in every file. I can neither login to my PC (windows 10) nor create another user via recovery on repair section. The ransom has blocked access to all domain users that they cannot login the same to local users. Whenever I try to login even with Administrator accounts both local and domain I get this message -“The User ProfileService failed the logon” and “The user profile cannot be loaded”- Can anyone help me how to get access back to my PC, decrypt my files and recover my data? I also got databases(QuickBook) included in my file, will you please specify what decryptor to use as I'm afraid that it may be damaged. Thanks
