virtualbox update? what to choose..

[asa]

awesome thanks so much! i am running 4.3.10 on a 32 bit machine i will go to that website and download it now, thanks all again! i am a little confused on which one to download, it lists a lot of them under that version of virtualbox? any idea which version of Ubuntu linux lite will go with best?

sorry for all the dumb question first time using virtualbox and linux in general.
