'You've got a virus,' my little sister said finally, sneering at me in a way that made it perfectly clear that she considered the whole matter beneath her. 'What internet security provider are you using?' I laughed, because internet security software is like ironing, or packing the night before a flight- done only by the neurotic or the elderly.
No piece of software is perfect or can ever be perfect. These imperfections within the code can be exploited by hackers to gain access to your computer. Once an exploit is found, it is patched by the software company which then sends an update to its users. This is the update that you keep ignoring.
Malware is malicious software which has been developed by someone (or some organisation) to cause disruption or, more commonly now, to earn them money. Your money. It wasn't always this way. Originally, computer viruses were created by computer enthusiasts almost as a game to see how many PCs they could infect.

But is this really the right approach to staying safe online?
