Well, I did get e-mail back from Symantec which is quoted below: This
does not answer my question as to how the infected file came to reside
on my computer when I have NAV running all the time and always have
the latest definitions????
There seems to be no way to get Symantec to answer a question like
this without paying big bucks for phone support. It's unfortunate as
I have been happy for years thinking NAV was preventing infections,
but it seems to have failed big time here! I wonder what this Trojan
would have eventually done if I had not run a manual scan of the whole
computer yesterday?
