latest list of viruses / malware signatures for F-Secure

I've got from majorgeeks & other sites : all of them ask to download
fsdbupdate9.exe (ie latest) & it can't install/run : I used 7zip to open
its contents but don't see any virus pattern file in it.

For TrendMicro, the lpt$vpn.xxx contains virus definitions & by issuing
   find/i  "name" lpt*  
it lists out the virus names

> go to the link and you should see the AV names added or updated
> https://www.f-secure.com/dbtracker/Aquarius/2016-09-05_07.html
Why is AV names being removed, thought they should just be adding on
to make it more complete?  Is there such thing as a malware/virus getting
obsoleted?

Btw, how do I identify from F-Secure's list if a malware is a ransomware?  
As long as the description contains the string  "lock" or "cryp" ?

But from https://id-ransomware.malwarehunterteam.com ,
there are ransomware with names that don't contain the above 2 strings, eg:
777
7ev3n
7h9r
ACCDFISAv2.0
Alfa
Alpha
AMBA
Apocalypse
Bandarchor
