I just read this article about spyware on your smartphone:

What anti-virus do you run, on what handset, and what's the impact on the phone's performance and battery life?

? On that cautious basis I run "Lookout" and "ES security". They do not seem to affect performance (although, as always, that is a very subjective statement!). I have not had any "infection" problems either, but being a scientist (of sorts!) I would in no way like to ascribe any cause and effect relationship between those two statements!!! But, it gives me some peace of mind and I guess that's what counts, at least until they possibly fail and I have to revisit the whole scenario
