Trojan Horse Virus


What is a Trojan Horse?

According to the Greek Mythology the Greeks built a huge wooden horse that was pulled into the city of Troy, pretending to be a gift to Athena as a sign of being undefeatable. However, the night after the horse was pulled inside the gates, a number of Greek warriors came out of the horse and opened the gates to the rest of the Greek army, leading to the destruction of the city and the ending of war.

Interesting fact… but how is that related to technology you ask? How can a huge wooden horse affect your PC? (Since it’s written as a virus in the title). Did the Greeks built a huge wooden horse to infect PCs? Well, the ancient horse itself is certainly no risk to your PC. But since the goal of the Trojan Horse was to trick the Trojans to pull the Horse inside their gates, leading to the destruction of the city, the term was then used to describe any act of trickery. Thus, one of the terms was used in computer literacy, the Trojan Horse Virus.

So? The Trojan Horse Virus…

Having explained the Trojan Horse, the Trojan Horse Virus is any Malware that is disguised as an authorized software tricking the user to run and execute it himself. The software starts doing its job, depending on the type of virus that infected the PC. Below is a list of the most known Trojan Horse Viruses:

So, how to prevent being infected by a Trojan Horse? Easy steps!

First of all, always keep your Operating System up to date, no matter what platform you are using. There are always security updates that need to be installed since the viruses are always improving themselves in order to attack newer systems.

Second, make sure to keep your anti-virus also up to date. As mentioned above, viruses take always new shapes and forms; so the anti-virus need to stay up to date in order to identify new viruses.
