Hacking happens AFTER you log on
Hacking happens after you log on: you get nailed by a drive-by shoot from some site that is suffering from "malvertising". Or you click on an eMail you think you need but which is actually a clever forgery,-- called "targeted phishing"
once you are "pwned" you no longer know what your computer is doing
there are two thngs needed IMMEDIATELY in the area of Computer Security
(1) Use an operating system which will not allow itself to be compromised by an erratic application program,-- whether by error or by intent.
(2) AUTHENTICATE all transmittals, particularly software updates but also financial records such as forms 1040, online banking and the like, and also eMail
you need both of these fixes
running with the current popular software is much akin to driving down the Dan Ryan Expressway on your inner-tubes
