I would like to know if you have any solution to decrypt files with the .davda extension.

All my files are infected and i. don't know what to do. Is there a way to decrypt?

I hope you help me, thank you

I would like to know if you have any solution to decrypt files with the .davda extension.

.davda extension virus is part of the STOP ransomware family. There is a decryption tool for older variants of the virus, but not for .davda.
You should remove the virus and try out the decryptor:

.davda Files Virus (STOP) – Remove It

Decrypt Files Encrypted by STOP Ransomware

If the decryption tool doesn't work, then you should wait for the malware researchers to update it.
