ClamAV/ClamWin. It's not a resident antivirus so you'll have to scan files you download yourself (or set some kind of trigger) which IMHO is better because it doesn't hog your PC when you don't need it.
Microsoft Security Essentials is good on Windows too. Microsoft has a bad reputation but it does a good job here.
You'll need a separate firewall, but Windows has one built-in and Linux has sooo many alternatives.
Also: keep your software up to date and do regular full-system scans just in case.

EDIT: care to explain the downvotes please? It's so irritating when you downvote legitimate comments without further explanation. Where am I wrong here? Is it just because I mentioned Microsoft?
Of course you can downvote but please do us all a favor and explain.
Microsoft Security Essentials + Windows Firewall (enabled by default if you install MSE) = probably good enough unless you visit a lot of shady websites. In fact, this is the exact same combination that comes with every copy of Windows 8.
