Silent viruses are silent in logs as well?

Unfortunately that means a variable number of reports per infected email (eg
one virus might be picked up by one antivirus engine, another might be picked
up by another, or by both, etc).   This makes it difficult to get a reliable
number of "how many emails containing viruses did we block today?"

Just out of interest, have I made an accurate diagnosis that viruses which
are not on the Silent list will result in the "Virus Scanning: Found n
viruses", and viruses which are on the list will not, or is the rule more
complicated than this?



In science, one tries to tell people
in such a way as to be understood by everyone
something that no-one ever knew before.

In poetry, it is the exact opposite.
