Thanks for the response.
You're dead right, when administrative control of a system is lost, you
cannot guarantee *anything*, VM or not :-(
Running Anything But Outlook/Explorer is the first, most beneficial
thing for any home user to do.
But Alt.Browser is not a complete solution - good to 80%?
I'll keep rummaging around for ideas, let you know what I come up with.
I have good friends (age 65+) up in Sydney who are "non-technical" but
quite switched-on when it comes to security and safety. Luckily their
"IT Dept" is very smart and quite expansive - but not always responsive
or available. What you get for free :-)
I got them to buy a 2nd computer and run it "air-gapped" for the
professional practice software supporting their business. They
understood the idea and embraced it. Also bought a KVM, made life a lot
easier and things all fitted on a small desk.
The Sacrificial Internet Machine (Ubuntu) died a while back and they
swapped to using a Winders Laptop.
The IT Dept hasn't given them a great solution for Internet Banking.
Currently they have a dedicated 2nd-hand/old laptop (Ubuntu?) that they
fire up just for Banking. Normally off and disconnected - hard to
compromise. But if anything goes wrong, they are at the mercy of Friends
and Family... Which has led to periods of great angst in the past.
[Who'd have thought - parents and grown kids with the odd problem?!?!]
But I'd like to come up with a simpler solution for them, *if* it
exists, that they understand and can manage themselves and will
withstand the variety of problems.
First cut, run a Linux VM on Winders, isn't good enough :-(
Thanks to everyone who's responded and given me good feedback. Much
