"Fact: Germs [including the flu virus] can live on surfaces for up to

Uh, yeah, erm...
Fact: Dettol kills 99.9% of bacteria. As does vineger, bleack, salt
water, soap, alcohol, and actually just about anything with an
osmolarity different from fresh water. :-P
Fact: Virii are not "alive" in the first place, so it is not possible to
"kill" them.
It does irritate me when commercial entities pray on public anxiety and
ignorance to try to peddle their wares.
And it /really/ irritates me when they pretend to be all scientific.
Seen any beauty products lately? Skin moisturisers have existed for over
a century, and they're all basically a specific mixture of water and
various oils. And yet, if you watch TV you see stuff like "Loreal
Age-Reperfect(tm) derma-active(r) hydro-therapy(tm)". All of which
/sounds/ really impressive and sciency, but is actually empty marketing
gibberish.
On reflection, maybe the problem isn't that commercial entities try to
exploit people. Maybe it's that the general populus are stupid enough to
not see though this...

It think if you have some unicellular organism (without being pedantic about
"cell" there, which after all just means "room" in latin), and you apply a
chemical that breaks up the cell and prevents it from reproducing, I think
it's safe for purposes of that discussion at least to say it was alive and
no longer is.

But virii are not unicelluar organism. They are very far from even being
one.
Virii are more like toxin: a chain of molecules, with the added bonus
that when encountering the right cells, they get replicated by the cells
(usually at the cost of the other functions of the cell, which induce
the exhaustion of the cell and its death).

Breaking a cell is easy, as the OP says.
Breaking a molecule requires to have an actual chemical reaction, which
usually means exhausting the reacting components. Moreover, you cannot
break a molecule and hope that the results will not be a toxic (or you
just lost in another way). You need to identify the molecule, then use
the right chemical to modify the molecule... the sad thing is that what
would break a virus would also usually break far more easily the
components of your cells.
UV-light might be of some help, if the radiation is strong enough, to
tear apart some virii (but not all). But beware also to not create a new
stronger one in the process.

Contrary to chemicals they will only replicate if the set of molecules
is in a specific configuration. If the case is broken they won't work,
nor if the DNA is broken up in parts or all aminoacids scrambled, etc.
In most cases people like them in the broken form. You might call that
dead, just as you might call a radio dead when in one tube the filament
is broken. Or you might prefer to use dead and alive only for
prokaryotes and eukaryotes.
De gustibus non est disputandum.
This thread is the first time that I consciously saw the plural virii. I
studied latin when I was younger (indeed at the end of the age of the
vacuum tube) so this strikes me as odd. Googling it reveals that only
the pedantic complain that this is wrong to the point of being silly. So
I won't complain.

That's why I said "for sufficiently loose definitions of unicelluar".
They're certainly a "cell" in the original sense of the word "little room".
They have walls, and a content.

Well, there's a small collection of chemicals with a distinct boundary that
self-replicate in the right environment. I think that's close enough to
"alive" for purposes of advertising.

Yep.

They're unlikely to self-replicate after you break them, tho.

We *are* talking about Dettol, right?
"Like other household cleaners, Dettol is poisonous and should not be ingested."
So, yeah, but that's a *good* thing.

Generally not. A virus is basically a little bottle of DNA that replicates
by injecting itself (with the help of the "bottle" part) into a complete
cell. The cell then gets hijacked by the virus DNA into creating more viruses.
A "germ" usually refers to something that includes the ability to replicate
all by itself.

I wouldn't say they are like toxins, nor are they "very far from even
being a cell". Virii have genetic material in the form of DNA or RNA, as
well as a protein coating. That's way, way more complex than a simple
chemical compound such as a toxin.
Prions also replicate (well, kind of), but are way simpler than virii
because they are, basically, just one single protein and has no genetic
material at all.
But even proteins are way more complicated than simple chemical compounds
such as toxins.

Except, of course, for those proteins that /are/ toxins. ;-)
