A hacker is a computer follower who enjoys programming, solving problems related to it, trying to increase computer capabilities, learning all the details of a particular piece of software, and so on. Sometimes the term hacker is also related to a person who gains unauthorized access to computer systems with some malicious intent. A hacker who is engaged in constructive practice considers this an offensive misuse of the term.

The practice of altering computer hardware and software to achieve certain goal is known as computer hacking and the people who engages in these activities are called hackers. Since the word “hack” is used in negative sense, some hackers claim that this term is disrespectful and fails to provide appropriate recognition to their skills.

The term computer hacking is most common among teenagers and young adults. It is considered to be an “art” form by many hackers who are true technology buffs and enjoy learning more about how computers work. They love programming and have expert level skill in one particular program. For these individuals, computer hacking is a chance to show their strength, and not always an opportunity to harm others.

Since most of the hackers are self-taught prodigies, some of the corporations actually hire these computer hackers as part of their technical support staff. These individual are basically employed by the firms to use their skills to find faults in the company’s security system so that they can be repaired quickly. This type of computer hacking helps prevent identity theft and other serious computer related crimes.

This term should not always be treated in negative sense. Sometimes, it can also lead to constructive technological developments. Many of the skills developed from hacking apply to more mainstream pursuits. There have been many hackers who have contributed in the constructive technological development, for example, former hackers Dennis Ritchie and Ken Thompson went on to build the UNIX operating system in the 1970s. Later, this had a great impact on the development of Linux.

There are also some hackers who have less noble motives, they use their skills to steal personal information, alter a corporation’s financial data, break security codes to have unauthorized network access. This type of computer hacking can sent you to a federal prison for up to 20 years.

If you are interested in protecting your computer against malicious hackers, then it is recommended to invest in a good firewall. Also, check your software programs for updates on the regular basis.

We have discussed ways and programs that help you improve your computer security, installing antivirus, antispyware and making backups, etc. But to be blunt, they are all secondary, not essential. To keep computer safe and secure on the internet, the most important method you should master is, to get yourself educated. I know a friend, a computer geek, and there is no security software on his computer. But surprisingly he has never got infected. We are not computer experts and I’m not persuading you to get rid of your security programs. I just say that educate yourself and form decent online habit can significantly help to keep computer safe and secure.

Educate yourself and be smart about where you visit and what you click on – Understanding how you can get infected and what to avoid when using the Internet will be the most important step in keeping your computer safe and secure. The majority of people who have infections on their machines were infected due to lack of knowledge and clicking on things that they should not. Here’s a list of actions under this step that you should not do:

1: Do not open attachments from users that you do not know. This is one of the most effective ways for viruses to infect you. If you can’t define the user, then simply do not open the email and delete it.

2: Never open an attachment that is a .exe, .pif, .com, or .bat unless you specifically know the file is clean. The majority of these are always bad!

3: If you visit a site and a popup appears saying that your computer is unsafe, ignore it! These are gimicks that are used to make you click on the ad which then can potentially install unwanted malware.

4: When you go to a site and a popup occurs, many times they will make them look like normal Windows message boxes in order to trick you into clicking on them. Instead just close them by clicking on the X.

5: Do not visit porn sites! I know some of you may not be happy about this, but the reality is that the majority of spyware and browser hijackers are put on your computer through porn sites.

6: Do not visit warez sites! Not only is pirated software illegal, but it is a breeding ground for malware.

7: Do not visit crack sites! Many of the cracks include malware in them!

8: If you use P2P software, make sure you are careful about what you open. Malware is all over the P2P networks.

9: Read the license agreement for any software that you install. Many free downloads are offered with spyware and other programs that you DO NOT want on your computer. Reading the agreement may help you to spot them.

You may have your own tips for this, and that’s very good thing. Getting yourself educated is the most effective and cheapest way to keep computer safe and secure. I know it’s a little bit hard at the beginning you follow these steps. Just force yourself to do so, and before long you will get yourself used to it. And at that time, there is little chance your computer falls.
