Hi, my computer has been attacked by RAA virus! It says that it has encrypted my files using aes 256 encryption. can I get my files back for free? Is there any chance? I really need them and I cannot forgive myself for being such careless. I believe this virus has hacked my computer after I downloaded an attached file from one suspicious email letter… Now this virus asks me to send a letter to Raaemail@example.com. Should I do that? Or is it dangerous to do so?
