If you are always online and you are afraid of being hacked, here are some of the things that you have to do in order for you to minimize the chances of being hacked.
The first thing that you have to consider is why a hacker would attack your computer. If your computer contains sensitive data such as financial information, you should definitely be more cautious whenever you go online. But if you are just spending your online time playing games, you probably do not need that much protection against hackers unless you are one of those gamers who spend thousands of dollars just for their games.
It is very important that you have dependable anti-virus software installed on your computer so that you will have protection against different types of viruses which, in fact is a common first step of hackers in gaining access to your system.
Whenever you enter your sensitive financial information online such as your credit card number, bank account number, or even social security number, you have to be very cautious. Make sure that the website that you are entering your data on is legitimate. Because there is what we call bogus websites which actually look like the real site but in reality, they are fakes. They were only created for the sole purpose of harvesting information from different people; this is better known as "phishing" or "pharming".
You also have to be aware that there are hackers who use their social engineering skills so that they may be able to gain access to your computer. That is why it is very important that you do not go with what a total stranger says to you right away especially if he asks for your username and or password. It is also interesting to note how large computer componant parts like the GE Fanuc Series, including the GE 90-30 don't really have these problems.
