Trojan Horses And Protection Of Your PC

April 06, 2010 By: lilybird Category: Software

You know already that there are different kinds of malware and spyware, such as viruses, spy programs, adware and computer worms, but now it is time to speak about a special kind of malware.

Maybe you hesitate to protect your computer and try to skimp on security of your PC, so understanding what threats are hidden in the links and how serious they are must help you to start considering on the proper protection of your PC. You know what viruses are but what is a Trojan horse? It is not a virus, because a virus reproduces itself, but a Trojan horse does not.

But what are these malicious programs and what they do to your computer? Those nasty programs do not make duplicate copies of themselves like internet worms do and they do not replicate. On the contrary, they may seem to be very helpful and legitimate, honest and friendly to your PC. They may appear to suggest you some help and to be your friend; they try to do some good for you but their background is malicious and carries tasks that are destructive on their basis and damaging to your computer. They can get control of your computer even without you think of it and they repeat it many times until it will be too late to change something. Such nasty programs usually gain access to your operating system and it is almost impossible to get rid of them. Thus, your computer must be well equipped with good protective programs to remain functional and healthy.

Developers of such malicious malware (very nice people indeed!) invented a great many various types of Trojan horses, such as keylog Trojans or key loggers, backdoor Trojans and some other nasty programs. Sometimes they can be two in one slot, for instance, both backdoor Trojans and keylog Trojans in one. This makes one program very powerful and it collects data from your computer and sends it back to those who then use your information against you.

As a rule, the hard drive of your computer is not screened by these programs in order to get information. Keylog Trojans monitor users (or loggers) record your actions and you will fall victim to these malicious programs when it comes to bank accounts or online business transaction. Thus loggers attempt to get remote access.

Such Trojan programs may be really very destructive and harmful to your database and your computer in general. It will easier for you to understand the necessity of protecting your personal computer if you know exactly what those programs do to your computer and what they have as objectives. The developers of such programs have one thing in mind: to make as much harm as possible to your machine and destroy it and to invade your private life and business information. Think of protecting your computer today but choose good antivirus software.
