- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
The Tunca cryptovirus could be set to erase all the Tunca Volume Copies from the Windows operating system with the help of the following command:
→vssadmin.exe delete shadows /all /Quiet
In case the above-stated command is executed that will make the encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore your data.
