Get a good antivirus. Is always better to pay for a antivirus, but there is some save antivirus free that you can download. just remember that you shouldn't have more then 1 antivirus, because they will start fighting with each other and the virus will get inside your computer just like a biblical plague of insects. I personally like the Microsoft Security Essentials, but there are others. doesn't really matter which one you have, just make sure you have one.
Make sure your Firewall is turned on. a Firewall is like a Extra security system that comes with your operating system. (operating system its the base software of a computer, like windows 7 for example, its where the rest of programs run on.) It makes harder for hackers to get into your computer and steal information. Still, a Firewall on its own is not enough, you will still need that antivirus.
There is a Program that I like very much. it is called Malware Bites, it not only helps keeping your computer fast, but it also helps against hackers with some extra protection.
Protect your documents with password. nowadays is really easy to protect your documents with passwords, that's one of the most important steps to secure your data. Just make sure no one else knows the password, and you won't forget it.
Use a password on your router. its really easy for someone who works with computers to get into your computer if they get into the same network as your computer is.
Use strong passwords. Not only numbers or letters, but some random characters as well. a password doesn't need to make cense, just make it random and hard to guess. once again, just make sure you remember it.
Be careful with the amount of personal data you put online. For example, Facebook is a great way to get people details. With your address for example, you could be getting pizza every 15 minutes and you would have to pay for that. Or annoying phone calls if they get your number.
Encrypting information is also a way to protect you data, but is not easy to encrypt something. The only way someone can unencrypt you document, is if they have the code.
Protect your computer by downloading the latest patches or security updates, which should cover vulnerabilities.
Common sense. You are responsible for protecting yourself, because at the end of the day, is anything REALLY safe? You are the one who have to be careful where and who you tell your details.
