Re: Denial of Service, Good for AS/400?

[John Hall <jhall@xxxxxxxxxxx>]

Just don't get it eh ?  I thought we settled this last year.  If you can
create an object on the 400 then you can create a virus.  You can't
create an object on your 400 ?????   How do you use it then :)

Give up the notion that you need to use a "boot sector" to be a virus. 
This isn't true on a PC and it isn't true on the 400.  The boot sector
is just a convenient place for the virus to hide.
