What Are Trojans?

Trojans are nothing but programs that disguise themselves as useful tools but perform harmful and sometimes troublesome tasks. These programs usually come in two categories, namely, the stand alone Trojan and the modified Trojan. The latter is usually modified and instructed by the hacker to execute some tasks. It is quite an irony that the Greeks offered a giant horse made from wood as a sign of a peace treaty to the Trojans, which had the Greek soldiers patiently waiting inside to attack, and the Trojan that computer users encounter today that equally offers horrible surprises.

Trojan Horse
This is a real Trojan Horse they used in the war. A computer trojan does not actually look like this...

Trojans are known to destroy important files, steal personal or confidential information and also making a hacker easy to take over your computer. However, they do not start running all by itself, it needs someone to activate it. Therefore, most of the Trojans disguise themselves as useful softwares, programs or even tools that make them look attractive to the users so that they are enticed to install them, rendering the Trojan to become active.

Iit is wrong to confuse Trojans with viruses, the simple reason being, that viruses have the ability to multiply, whereas Trojans don’t. Trojans are similar to spyware in a way and are also installed unknowingly by the users. These programs are created by computer professionals who are experts in what they do. They create these Trojans in the form of crime-ware so as to trade them in the black market mostly for fraudulent purposes. The professionals who create these programs are known as crime-ware authors. Trojans are successfully programmed to hide themselves and corrupt the user’s computer.

Threats Found!

However, it should be remembered that installing the Trojans is only the first stem towards your computer destruction. Trojans are actually programmed so that they can install/download threats that are even more malicious, namely, bots and other and other harmful programs. Trojans can also be forwarded to users by way of e-mail where the Trojans disguise themselves as some video clip, an image or even a fake URL. These e-mail attachments are usually sent anonymous senders. The Trojan horses are susceptible to Microsoft Internet Explorer. Trojans are seen to contain extensions like .exe, .bat, .pif, etc. Trojans are known to affect the computer in the following ways discussed below:

  1. Trojans are known to download additional malware to harm your computer.
  2. Combined with other malware, Trojans erase and overwrite existing data on your computer.
  3. Giving access to intruders to your computer through “backdoor” creation.
  4. With regards to spying, Trojans are known to record keystrokes and sending them to an intruder enabling him access to credit card and password information.

If you get the slightest idea/sign about the existence of any Trojan in your computer, its time you get rid of it. Firewalls and anti virus softwares are known to keep Trojans at bay. Even if you have an anti spyware installed, Trojans won’t threaten your computer.
