Why don't you have added a virus to the database?

Hi!
Why don’t you have added a virus to the database?

A few days ago i am send you a virus (file name: GUESTS_IH.exe) that steals passwords to the Russian social network (www.vkontakte.ru).
The virus modifies the HOSTS file, then loaded the pirate page instead of original, you enter the password and send it to hackers!
I have attached a description, but the virus has not been added! Why? Perhaps because the sites at which to redirect not working now?
Virustotal report:

Question №2 (the main):
Why Avast not responds to changes in HOSTS file?

Thx.
