To try and keep up with security etc. would it be feasible to buy a new (cheapish) machine for the sole purpose of web use, leaving the (inevitable) build up of stuff on an existing desk-top, which would have no contact with any-thing risky. All the online stuff could then be allotted to the new machine. The existing screen could be used with a simple manual cross-over switch.
Any further ideas most welcome.
