I used the "avast_decryptor_targetCompany64" tool to decrypt it. After the third step, I have to enter a password to proceed to the next step, but I have not decrypted it before, so there is no password,

Did you submit (upload) samples of encrypted files, ransom notes and any contact email addresses provided by the cyber-criminals to ID Ransomware (IDR) for assistance with identification and confirmation of the infection?

Are you sure the encrypted file extension is .avast?
The TargetCompany ransomware has several variants - .avast doesn't appear to be one of them.
