There is a very simple way of demonstrating the problem of viruses on her
PC to her. Install a modem in the PC and connect it to the phone line. It
won't be long till she gets one of the the viruses that dial a long
distance location. Her next phone bill will demonstrate to her why having
a clean PC is important.

This has worked for my in-law. He was the one who plugged the modem back
into the phone line after I unplugged it and told him no to have it
plugged in.

Yeah, that sux.
Someone should fix that.  Get right on that, would you? :)
In the mean time, tell her not to deal with the pop-ups, just remember 
to click Start -> Windows Update _herself_, manually, once a week or 
so.  And install a virus checker.  Oh, and since you know what you are 
doing, lock her system down so nothing can get in, since she only uses 
it for web browsing.


2) she "only uses the pc for web browsing, if it gets infected theres 
no harm
that can be done"

So how do you argue with that?
If the idea of spewing millions of spams to other people does not 
affect her, you could threaten her with violence.

Also, a lot of people who "only do web browsing" sometimes "browse" to 
their bank

I think we have to learn to explain to the "normal" people, without scaring
them too much, that their PCs are part of a big online world whenever they
are online - which is almost always in the world of broadband - and that
even if they don't feel directly affected by Internet bourne viruses, their
PC can be turned to "evil" purposes without them knowing and that it is
their duty to behave properly in this online world.

Agreeing somewhat with Paul Vixie's earlier comment about learning to use
the right analogies or not using them I am still going to try - because when
we speak to these "normal" people, they need analogies to help them
understand.

So with that in mind; while you may not care while inside it if your car
develops a failt and belches smoke and pollution everywhere, you should care
because of those other folks on the road and roadside while you are driving
it past - not to mention the additional costs in fuel and oil and so on - or
in the PC sense, the whole machine can become sluggish and perform poorly
when not well maintained as well as causing others grief.

I was looking at a friends PC, her mother uses it and she's a bit of a 
technophobe... I was upset that it hadnt had any of the windows updates 
installed since last time I looked at the PC a year ago even tho windows was 
popping up all the time pleading to be updated!

I attempted to explain the whys and what fors and was surprised at her 
reaction.. she still didnt want to run the updates even tho she now understood 
what they do. 2 reasons:

1) she's overwhelmed by the amount of things that pop up at you, ask you to

opening attachments from unknown senders in the last year, 29% used their
own name or birthday as a "secure" password, 17% accessed the company
network in a public place and didn't log out, 9% informally shared
a network password with someone outside of the company.

The survey included relatively few people, 254 executives from Europe,

Sean quoted some numbers sometime ago for 'average cost of virus outbreak
per enterprise' I don't recall the specifics, but they were staggeringly
high... On a whim/notecard lets try this:

1) enterprise network with 10,000 user systems (we'll assume no 'servers'
got/get infected in this ficticous dreamland of an example)
2) 1 user clicks attachment and gets  which spreads to 50% of the user PC's before action is
started to clean them.
3) assume a 'large' infosec/helpdesk group: 20 people
4) assume average cost per sec/help employee at 100,000/yr (including
benefits+OT for this incident)
5) assume all other sec/help work stops to stem the virus flow
6) assume it takes 1 day (complete 14 hour day) to cleanse the bad
machines (5k machines, which is 5000/20/14 = 17.8machines/person/hour or
3.3 mins to clean each machine and move to next machine... 'lightening
fast staff'!)
7) So for 1 day we tied up 20 people for 14 hours:
  10/1880*8*20 + 10/1880*6*20*2 = $21276.60

That accounts ONLY for the sec/help people to do their 14 hours/person of
work (assuming 2xnormal OT rate, count that out and its still: $14893.62)

No, keep in mind that during this 14 hours the following other things did
NOT happen:

1) 5000 people doing their normal job due to their PC being dead
2) 20 sec/help people NOT doing their normal work
3) 1 exec still happily playing solitaire...

These calculations are 'back of the irc-bot' calculations, and do leave
some things out... for instance server outages due to virus infections,
service outages due to network outages, lost revenue due to service
outages or lack of capacity to manage customer
requests/complaints/orders/blah...

These events are highly costly, no matter how many times we make this
arguement it's not clear that anyone that should be listening IS
listening. Often the resulting response is: "Well, buy more/better virus
protection software!" (from the same clicker-of-attachments) or "Shouldn't
our AV have caught this?" AV is but one part of the equation, user
education and consequences are some of the other part(s).

you'd sure think it would, sadly it doesn't seem to...

Tell them that every time they click on that thing, it costs $1000
to disinfect the LAN and keep the firewall up to date.

Caveat: have yet to actually try this approach, but seems like it would
have a chance at least.

surprised? if you don't teach the baby the consequences then they continue
