The best offense is a strong defense. Nothing works better against threats than simply avoiding them. Fool proof. More people need to be better educated about their online activities. Alas, there are still many newbie/novice/ignorant folk who use the Internet, just waiting for the mal-folks.
I really think someone needs to come up with a simple safety browser, that can allow people access to their websites of interest only, and be scrutinizing of those to be newly added. Also, e-mail attachments should be facilitated with better analysis/filtration.
