Trojan removal

I am running NIS 5.5 on OSX 10.8.3. A TROJAN is reported everytime I do a FULL scan. img3427390789.zip. Norton reports but does not quaratine it but also says it can't repair it. The infection appears to be mobilebackups but I can't find it. Anybody got any ideas how I can "simply" get rid of this beast. I was hoping that this is what I was paying Norton for!
