TBH, I have not tried any AV for the phone just yet.. there is not much at as far as viruses for android just yet that I have seen or heard of.. i use titanium backup for backup/restore options and I have Android lost for anti theft.. with AL, i can send texts to my phone to wipe it, lock it.. i can locate it and it found me within 5m or so and emails me the googlemap screenshot so you can see exactly where it is.. great app so far and free. so, for now.. not gonna bog my phone down using up more resources for an AV since it does not appear to be a huge threat just yet.. jsut my 2cents zug
