Threat detected cannot remove from Macbook: JS:Nimda-B [Trj]

Hello Tristan,
We are sorry for the inconvenience caused.
Could you please attach the screenshot of the AVG Scan window here?
Thank you.

Hi,

I have a Macbook pro for which I downloaded AVG anti-virus protection. I did a routine scan and following threat was detected:

JS:Nimda-B [Trj]

When I selected "protect me" I got message: "Cannot move to quarantine" so I selected "delete" and got message: "Some files cannot be deleted, sorry, some infected files cannot be deleted, but we've safely blocked access them"

My question therefore: What is this JS:Nimda-B threat? And how can I completely remove it from my Macbook pro?

Thanks

The same thing is happening to my mac. I have uninstalled and reinstalled. What can we do to remove this virus?
