WHAT IS TROJAN HORSE

Welcome to Hackers World!!!!!

Hi Friends today I am going to tell you about Trojan horse. but First of all I would like to tell you the Difference between Trojan , Viruses and Worm. Some people think that Trojan and virus both are same but I will tell you what the differences between them are.

Trojan horse- It is a program, using this program it will make the victim system to make listen on particular port, so that attacker can do anything on your system, i.e. he can tamper with, steal, and destroy the data etc...., a Trojan horse won’t spread in to the system like a virus so it won't effect the system performance.


virus- It is a malicious program, using this program it will damage your system, by injecting the virus in to another programs are files, so that it will regrade your system performance. Virus will come to the system with user interaction only.


worm- It is also one type of virus, using this program it will damage your system like virus, not only system it will spread through out the network and checks for honey pot of your os, and enter into the os, it will regrade your system performance and also it will eat your network bandwidth.

Trojans are executable programs, which mean that when you open the file, it will perform some action(s). In Windows, executable programs have file extensions like "exe", "vbs", "com", "bat", etcTrojan may allow a hacker remote access to a target computer system. Once a Trojan has been installed on a target computer system, a hacker may have access to the computer remotely and perform various operations, limited by user privileges on the target computer system and the design of the Trojan. Some Trojan horse viruses will simply be annoying and will not necessarily harm your computer in any way, while others can and will be able to cause serious damage to your computer by deleting files and destroying vital information on your system

How to protect from Trojans
There are several steps that you can take to protect your computer from viruses such as Trojan horses. You should always make sure that your operating system is up to date. You should never go without antivirus software on your computer, and you need to remember to use this frequently, about once or twice a week. You must make sure that you are consistently getting updates on these programs. You will also want to make sure that the antivirus program which you have has the ability to scan emails and other files which are downloaded from the Internet, as this is the primary resource where computers are attacked by viruses.
