Modern Windows is fine, too. You may even be able to use Windows 7 that way these days. A lot has changed since XP SP2.

I use windows 7 since >10 years, without firewall, virus scan and only with handpicked updates. As long you live behind a NAT and use a modern browser and mail client, nothing will happen. No viruses, no botnets, no malware.

I didn't test this with a virus check, but I have a bitcoin wallet with 0.1 BTC and without password on my HDD. Still there.
