You're obviously free to make your own risk assessments, but you seem to be working on some seriously wrong assumptions:
Believe me - the risk of being infected by malware, on a modern OS kept up to date, with a modern browser kept up to date and on a typical LAN connected behind any half decent router running NAT is tiny. I really do mean it - you'd have to go out of your way to end up with malware on the PC.
False. Witness the aurora incident:

Those were all up-to-date pcs, running corporate antiviruses, behind a firewall and NAT.
Some of those were on state-of-the-art corporate networks (e.g., Google).
You are working under severely misguided assumptions. In today's corporate world, zero-day drive-by downloads are common and scary.
This is what I study for a living ;-)
