Unable To Access Files Encrypted By 3rd Party Folder Lock

Hello! I have a Folder Lock 7. I have encrypted 100GB disk to that, out of that 46 Gb was occupied. Recently my external hard disk was infected by virus and when I removed the virus thereafter I am not able to access the files inside the Folder Lock. I’m able to Unlock the Drive with the password but the drive is not accessible.
Please Help.

File was locked using Newsoftwares’s Portable Folder Locker.

After unlocking I get the dummy drive and when I try to open that I get an error message saying “Z:/ is not accessible. The file or directory is corrupted or unreadable”
