hi recently been presented with a sony tablet for my birthday and was wondering what is the best anti virus software for use with the tablet.

i have homesafe by talktalk at home with 3 user licence and would like to knoe if this would work ?

or do i extend my antivirus software from norton 2012 to include my tablet  ?

or better still ? use AVG Free antivirus software ?

as users of the sony tablet what would you do ....
