[Kaspersky failing to detect a .mmvb ransomware]

@Berny:  I use a Windows 7 whilst the emsisoft Decryptor Tool seems to be only for Windows 10 64 Bit and above.  I need to know, if I manually or Shft + Del all the infected files , and also the files from my portable Hard Disk, will this be enough?  Or, should I format the disks?  Will be malware be gone if I reinstall windows ?

[Kaspersky failing to detect a .mmvb ransomware]

Hello,

These are my system details: 

 

Application name  Kaspersky Internet Security
Application version 21.3.10.391 (j)
Operating System Microsoft Windows 7 x 64 Service Pack 1 Build 7601

I've been running a fairly new version of Windows 7 until being infected by a ransomware.  It seems to be named as .mmvb ransomware.  I've done a Google Search and understood that after attaching the .mmvb extension to all documents in my PC it'll ask for a ransom.  The problem is that after installing Kaspersky Internet Security and running a scan, it's failing to detect the virus / ransomware.  I've added screenshots of a sample .mmvb in my Desktop, one in my Pen drive, and the result of a scan of my pen drive.  Should I reinstall Windows ? Thanks for the help.
