Thing is, it seems to be constantly connecting to public open networks when I'm not looking - which is good for following the Twitters, accessing emails, and downloading The Guardian etc, but is a bit disquieting if one finds that it's made several connections on the way into town some of which may or may not be safe or even genuine.
Notwithstanding that the smartphone is obviously smarter than me, the fact that it's so eager to connect to the internet suggest I need some sort of firewal program an' ting. But there's a monsterously humongous list of security type apps on the Google Play site and actually discerning which one does what, how, when, and why is not so easy. One might generally go for a top brand, but reviews are distinctily patchy on Norton and AVG etc whereas some ugly-iconed Free app I've never heard of might get favourable reviews, even if it's only from 12 people.
It's a minefield of a mindfeild, so any recommendations or disrecommendations from more experienced Android operators would greatly aid my cogitations.
Is it better to get separate virus protection and firewall or go for an all in one? Freebies or payforit? Configurable or automatic? That sort of thing.

Also, which is better alternative to the Samsmug browser for the forum: Chrome, Firefox, Opera, Safari, or something else? It's all soooooooooooooo tiny, and making it big gives me wrist ache (which funnily enough is not the first time I've typed that!).
