Can't remove trojan using Norton for Mac

Hi 

I'm using Norton for Mac and OSX Lion 10.7.5

I keep detecting a trojan (see below) but it can't be deleted even using terminal and the sudo rm command.

The path is :

MobileBackups/Computer/2012-11-19-115440/Volume/Users/MYNAME/Documents/Microsoft User:

The Trojan is a 2.6MB 'document' file called

x27_68349.olk14MsgSource

 

Can you help?
