For many people, malware seems to have many weird names, like worms or ransomware. And what are trojan horse viruses? To start, trojan horse viruses are a type of malicious software designed to disguise itself as a legitimate application to get into the computer, then it works silently in the background to hide its malicious activities.
The term trojan horse originated from the Trojan War story. A wooden horse filled with murderous Greeks led to the destruction of the Troy Kingdom.
In computing, a trojan horse works in much the same way. It pretends to be a useful application to lure in victims. Once installed, a trojan horse is harmful in many ways, which is why it’s important that you know what are trojan horse viruses.

A Trojan horse creates backdoor access that allows a hacker to take control of the computer. It alters the security setting of the device to gain administrator privileges and create a backdoor without being exposed. Backdoor access allows the hacker to copy, delete, and modify critical data on the computer. That’s what are trojan horse viruses and what are they capable of.

The attack may last from a day to a month, depending on the severity of the damage and incident response of the company. This is big reason they are so dangerous and learning what are trojan horse viruses is important.
Conceals Malicious Activities
A trojan horse can be programmed to load and execute directly from computer memory, enabling it to modify critical data.
