Steam?

I second Steam: http://store.steampowered.com/

You have to download and install the Steam client, but when you buy games they are saved to your account and you can re-download and re-install them at any time.

I use Steam alot - it's my favorite PC gaming store/service. Good Old Games is another, but with a smaller more curated selection mostly focusing on older games.

I also use the Humble Bundle Store when they have good sales going (and then redeem my Steam keys on Steam ).

Impulse (GameStop), Desura (ModDB), and Origin (EA) are the other 'major' players (though all of them combined are still smaller than Steam).

Also, Windows 8 does have an actual app store, though I don't know how much is actually on there.

If you are worried about software being malicious BTW, make yourself a new user account (without admin privileges) and run it from there.

Or consider running a full VM to isolate the games.

Or just get the virus, battle through whilst trying out different bowling games and then finally wipe your computer and reinstall a clean OS. PCs are good like that in that they are not locked down. You can't really brick them (unless you want too. Freedom!).
