My recommendation is no.
If you really feel you must then use ClamXav. It is one of the least obnoxious of all of the AV software and it is free,

As of a couple days ago Apple addressed this with a recent software update. Run Software Update and install the recommended Java Update and the "Flashback removal tool".
The recent trojan was not transmitted from Mac to Mac, not through email, and not through Skype. No such methods are known to have affected Macs. The trojan was downloaded to individual machines through fraudulent Adobe Flash installers or malicious websites.
Do not purchase any third party "virus protection software", all are either worthless or harmful.

If you feel you really want something then I'd suggest the (free) Sophos Anti-Virus package.

If it was the most recent trojan, then you can rest assured that you didn't get it from her. This trojan did not transfer just through communciation between mac's. It was transferred by going to pages and running Java on the pages that would give you the virus. This has however been fixed by apple and there is an update that you can run that will help you remove it if you have caught it. However, there are a few Anti-Virus programs out there that are free, but the way that this new trojan is out there, most Anti-Virus programs out there can't detect it, and even the ones that can, can't detect every strain of it. There really is no full proof to guarantee you won't get it, it's all in how safe the user is with the computer, but as stated, you don't have to worry about getting it from her from an e-mail or even staight Mac to Mac communication. It's passed on to the computer through a security flaw in Java.

So as a very basic user I have a very basic Q, when you say "do not purchase third Party" virus protection, is there already an Apple virus protection on my Macbook or basically no need for such protection at all?

Anti-virus software has been an integral part of OS X for at least its last two releases. No other (third party i.e. non-Apple) AV products can be recommended. The best they have been able to do, including addressing the recent Flashback trojan, has been absolutely nothing. The worst examples are known to have resulted in data loss, random crashes, OS corruption and other headaches.
The best anti-virus protection is between your ears. Far too few people use it.
As far as "protection" is concerned I recommend using OpenDNS. This is not something you install on a computer; it is a setting in your router that will prevent the possibility of your Internet service provider's DNS from becoming hijacked or "poisoned". OpenDNS has many useful features, is totally transparent to your computers, works with all the devices on your home's network including Macs, PCs, iPhones, iPads etc, and is absolutely free.

There's no easy yes or no answer, it's a personal choice. But what you MUST do is educate yourself about the threats and how to protect yourself. See my Mac Malware Guide:
