These numbers indicate you have nVIR strain B.

Look for the following in your System file:
Type   ID   Size B
----  ----  ------
INIT   32     416
nVIR    0       2
nVIR    1     428
nVIR    4     422
nVIR    5       8
nVIR    6      66
nVIR    7    2106

Good questions, to the best of my knowledge nVIR spreads to the
System as soon as the first infected application is run, then after
reboot spreads to any application run.  Were you using any sort of
virus blocking INIT (eg. Vaccine, GateKeeper)?

My best advice is to pick up a copy of Disinfectant (available many
places) which is a free virus detector/remover written by John
Norstad of Northwestern University here in Chicago.
