Trojan horses are a form of malware so deceptive that you would hardly know you’ve been had. Although most recent update virus definition files of antivirus firewall software programs are capable of detecting many trojan horses, some trojans are still unidentified and continue to spread around the Internet.
Trojan horses got their name from the classic epic tale of war known as the Trojan War. In the story, the Greeks were trying to defeat the city of Troy. Odysseus, who headed the Greek warriors, thought about using a deceptive strategy in order to gain entry into the Trojan city. So, he ordered his men to build a big horse made of wood. The wooden horse was big enough for several soldiers to hide inside its frame. Once the horse was ready, and the soldiers concealed inside it, the Greeks offered the wooden horse to the Trojans as a peace offering. Wanting peace more than further bloodshed, the Trojans accepted the gift and allowed the horse into the city. The rest, of course, is history. Troy fell because it became vulnerable.
Trojan horses, the computer malware that is, work in the same way. First, they trick you into thinking that they are legitimate or useful programs. Perhaps, they can deceive you into believing that they can increase your network speed, or maybe make your computer run faster. But, once you run the trojan horse program, it releases the “soldiers” hidden inside it. In computer parlance, those “soldiers” are called the payload of the trojan horse program.
The payload of a trojan can be a computer virus, a network worm, or some other malware that can be destructive once it enters your system. The payload would have been perfectly harmless had it not gained entry to your system through the trojan masquerading as a useful program.
Is there a way for you to unmask the deception before your gullibility can get the better of you? Yes. Though not perfect, an antivirus firewall software program can easily spot the well known or identified trojan horses. So, your protection program can immediately alert you of an impending threat.
