Do you know the difference between computer worms and Trojan horses and what is their role in infecting your computer? What are they and how do they act in your machine? Can you protect your database and your computer in general from those computer monsters?

PC worms were created for travelling; they go through networks and make copies of themselves. They are able to reproduce and spread like viruses in the body, but the ways worms and viruses spread are different. While viruses require files to spread and they are dependant, computer worms spread themselves on the internet.

The ways of spreading are unique for each computer worm. They can spread themselves through files very quickly and infect each computer in a network. Some computer worms can copy themselves so many times that they left operating systems corrupted and damaged.

E-mail worms are the most common. They spread through e-mails when you click on the attachment of the received message, because links and attachments are the ways of infection. Those who create such programs have only one target and their target is to destroy. You should not fall victim to these malicious programs and their dishonest developers. Stop the chances of being infected and protect your computer right today, because the damage may be prevented before it occurs.

As for Trojans, you should know that they are not viruses at all, because Trojans do not reproduce themselves, viruses do. This type of malicious programs behaves like your friend, suggests you some help and tries to be useful; but it runs damaging and destructive tasks in its background and corrupts your database and your PC. It receives control of your computer and you do not suspect it until it is too late. If your PC is not equipped with the protection, it will be very difficult to get rid of this malicious program. Although unlike computer worms these nasty programs do not make copies of themselves and do not replicate like viruses.

Trojan horses may be of different kinds such as keylog Trojans or key loggers, or backdoor Trojans, or some others. Sometimes one program may become twice as powerful if backdoor Trojans and keylog Trojans are both in one shot. They collect information from your PC and send it back to some third party observer and that ?collector? uses your information to get some profit from your personal data.

Keylog Trojan monitor users get remote access to your database, their programs do not screen your hard drive to get data; they record your actions many times and get access to your bank accounts or business transactions. Trojans are very destructive programs and you should understand the importance of protecting your cherished computer from all malware.
