I really like my first Mac so far. So much so that I am installing Windows on it.

I really like it. This is my first Mac, and I looking forward to learning how to customize and utilize this OS to the fullest. I like it so much that I'll keep it and install Windows 7. That's no slight. No, au contraire, I mean that as praise! If I didn't want to put Windows on it, I wouldn't want to use it as my primary computer.

Furthermore, my rMBP was flawless. No scratches, nicks, or any unsightliness on the outside (why would it be anything else?). The screen has no dead pixels, the backlight is even and bleeds very minimally (less than my excellent IPS LCD monitor that I've been using for the last year). There are no pressure marks, etc. I guess it was worth waiting until the 13th of July to order.

Oh yeah, I could use one bit of advice: Do I need to install some sort of anti-virus/malware/etc. application? If so, what's good?

Yeah, I use Microsoft Security Essentials on my Windows machines too. It's super lightweight and I can't even tell it's there. Combined with common sense I've never picked up any viruses or malware.

If you're talking about the OS X portion I don't use any anti virus. Just common sense.

For your Windows installation, you may. As for the Mac, Macs are not immune to malware, but no true viruses exist in the wild that can run on Mac OS X, and there never have been any since it was released over 10 years ago. The only malware in the wild that can affect Mac OS X is a handful of trojans, which can be easily avoided by practicing safe computing (see below). Also, Mac OS X Snow Leopard and Lion have anti-malware protection built in, further reducing the need for 3rd party antivirus apps.
  1. Make sure your built-in Mac firewall is enabled in System Preferences > Security > Firewall

  2. Uncheck "Open "safe" files after downloading" in Safari > Preferences > General

  3. Disable Java in your browser (Safari, Chrome, Firefox). This will protect you from malware that exploits Java in your browser, including the recent Flashback trojan. Leave Java disabled until you visit a trusted site that requires it, then re-enable only for the duration of your visit to that site. (This is not to be confused with JavaScript, which you should leave enabled.)

  4. Change your DNS servers to OpenDNS servers by reading this.

  5. Be careful to only install software from trusted, reputable sites. Never install pirated software. If you're not sure about an app, ask in this forum before installing.

  6. Never let someone else have access to install anything on your Mac.

  7. Don't open files that you receive from unknown or untrusted sources.

  8. For added security, make sure all network, email, financial and other important passwords are long and complex, including upper and lower case letters, numbers and special characters.

  9. Always keep your Mac and application software updated. Use Software Update for your Mac software. For other software, it's safer to get updates from the developer's site or from the menu item "Check for updates", rather than installing from any notification window that pops up while you're surfing the web.
That's all you need to do to keep your Mac completely free of any Mac OS X malware that has ever been released into the wild. While you may elect to use it, 3rd party antivirus software is not required to keep your Mac malware-free.

If you still want to run antivirus for some reason, ClamXav (which is free) is one of the best choices, since it isn't a resource hog, detects both Mac and Windows malware and doesn't run with elevated privileges. You can run scans when you choose, rather than leaving it running all the time, slowing your system. ClamXav has a Sentry feature which, if enabled, will use significant system resources to constantly scan. Disable the Sentry feature. You don't need it. Also, when you first install ClamXav, as with many antivirus apps, it may perform an initial full system scan, which will consume resources. Once the initial scan is complete, periodic on-demand scans will have much lower demands on resources.

I use MS Essentials for my Windows partition. Nothing for Mac. All is well.

And GGJ, your "canned" answers have helped me numerous times. You don't have to explain yourself to anyone. Good information is good information, no matter how you slice it.
