Who would want to break into my Home/SOHO PC ?
Intruders (a.k.a. crackers, or hackers) do not necessarily care about your identity, they often want to gain control of your PC so they can use it to launch attacks on other computer systems...
Having control of your PC gives intruders the ability to hide their true location as they launch attacks, often against high-profile computer systems such as government or financial systems. Even if you have a computer connected to the Internet only to play the latest game, or to simply to send email, your computer may be a target.
