Not per se. But the argument about not wanting to break concentration doesn't
really fly if one is constantly interrupted by coworkers either...

What ? You prefer viruses ? virusses ? Viri ? Virea ? Virux ? ;-)

Well, whoever said 'large' companies are the only ones that matter?
In my experience having multiple brands happens often. In some cases they may
deploy a filtering mail gateway that's bundled with a brand X virusscanner.
In other cases they may find that brand Y on the desktop offers better value
than using brand Z which they equipped their exchange server with...
In any case, deploying multiple brands IS a good practise, security-wise.
If a buffer overflow (or a botched Datfile update) is found in one product it
will probably affect their whole line of products. That's bad. Then let's
consider the various timezones; using european and US AV products can
sometimes give you the few hours advance that you need to avoid a disaster.
If you want 4 locks on your front door, would you buy four locks of the same
brand ? (or even, for paranoid people like me: would you have them all
installed by the same guy ?) For me, the answer would be a resounding NO.

Yes they do. But I hardly think it is LESS work for them to track all those
"aka" names and versions to include in their description pages than it would
be to standardize after the fact on one single name for the virus. Right ?

Well, precisely. You hit the nail on the head...
It happened on SO many occasions to me that the installed AV scanner did
identify the virus but was unable to remove it (or it instantly came back
after "removal") that I had to hunt down a different (better) removal tool
(rescue-CD, dedicated removal tool, or otherwise).
It is at those moments that all the aliases in use for the virus bite you.
