You will see a lot more -- this seems to have gone ballistic...

BTW, NAV detecting it as "Novarg" and Trend as "Mimail.R" is just 
another case of multiple labs working on the same massive outbreak 
independently before realizing just how widespread it was (or at least 
had realistic potential of reaching).  I have heard from analysts at 
Symantec that they will rename it Mydoor to be in keeping with the bulk 
of the other developers, and Trend is pretty good about renaming things 
in such situations, so I guess they will follow suit too.
