You'd be safer than your computer If you danced in front of a lion that was on crystal meth...
Historically speaking, any computer that is connected to a public network and running a Microsoft Windows operating system is more vulnerable to attack than any other operating system. Particularly, out of date, and unpatched versions of windows are worse off than otherwise. This is due to several factors - Windows Operating Systems usually have more security vulnerabilities than other operating systems do, but mostly they are more vulnerable because of the popularity of windows. There are many more people using Windows than other Operating Systems, so there is more incentive for hackers to target it.
Many things from the coding itself to any information that can be accessed by the hacker. It depends on how deep the hacker has gotten into the system.
D.D.O.S every one, no matter the operating system is vulnerable. See related link.
There are 5 files in Windows 7, but DO NOT tamper with the system because it can damge your files and erase memory thinking that it is an online hacker.
The scope that a hacker can use to break into a system is often referred to as an "attack surface." This includes all potential points of entry, such as software vulnerabilities, network interfaces, and user access points. By identifying and exploiting weaknesses in this attack surface, hackers can gain unauthorized access to a system. Effective security measures aim to reduce the attack surface to minimize potential vulnerabilities.
Any malware may not attack a given system if it is targetted to a specific system. Unix systems are vulnerable to viruses and malware just as other systems are.

Viruses attack weak points in the Windows operating system and so they do not affect the Mac's operating system. If you are running Windows on your Mac then you will need to ensure that your Windows installation is protected.
A backup for Windows is always recommended because the operating system is vulnerable to viruses. Sometimes the only way to get rid of them is to start with a clean slate.
Penetration testing is a process designed to evaluate the security of a computer system or network. A mock attack is staged in order to determine whether the system is vulnerable to attack. Suggestions are then made to the system's owner, in order to improve security.
There are no viruses that attack Mac OS X so antivirus software is not needed unless you are running the Windows operating system on a Mac then you will need suitable protection against the thousands of viruses that attack the Windows operating system.
