It's an interesting thought... Symantec seemed to think Inner space was acting like a keylogger after it updated itself in the last couple of days. But I haven't been hacked yet. so can't say I'm too worried. Not all of my accounts have authenticators on em yet.

One of the simplest and easiest things one can do beyond AV/Firewal, windows updatesl etc etc is use Firefox instead of Internet Explorer. While far from full proof it generally seems to be a safer option when surfing.
