Your BitDefender did not manage to block the ransomware before it spread? Ransomware won't simply attack your computer if you didn't do anything hanky pranky.

How ransomware spread and attack their victim?
1. Download and install illegal/pirated software/games
2. Browsing to video streaming websites (porn or non-porn)
3. Visiting to porn or illegal online gambling websites
4. Malicious email attachment or links thru email
5. Someone purposely inject the malware onto USB storage and share it to you
6. Someone on the same network got infected by the ransomware and it spread across network thru share folder

Basically, DJVU ransomware is not that new anymore and those file which encrypted by ransomware cannot be recover. Just forget it unless those data encrypted worth over 6 digits. There are many case that corporate paid to the ransomware creator but it didn't manage to decrypt back all files 100%.
