In some cases, ransomware installed by Trojans can prevent the user from logging into the computer’s operating system. If this is the case, the PC must be booted in a security mode. This will stop the Trojan from loading when the user logs in. The alternative to scanning viruses that does not require Windows access is a bootable antivirus program. This runs on portable devices such as data carriers or flash drives and scans a hard drive for Trojans without even starting the operating system.

Likewise, Trojans often come from freeware and shareware that the user has downloaded from the Internet. Although not all freeware is a Trojan, it is recommended that you download software and freeware only from trustworthy sources. Often, attempts are made to distribute Trojans via pop-up pages, which tell the user that the computer is infected with malware and that some antivirus software should be downloaded to remove it. The suggested antivirus program then turns out to be a Trojan, which installs malware.Ī trojan can only work if the user launches the program. Once it is running, the Trojan can begin installing other software on the computer. Trojans can have several functions, depending on the attacker’s motives. The Trojan itself is only the vehicle for the corresponding payload.Ī Trojan horse scanner is required to scan your computer for Trojans. If a Trojan horse scanner or anti-virus software is already installed on the computer, this should be updated before the scan process. In addition, all temporary files should also be deleted in order to speed up the virus scan. Instead of the standard quick system scan, a complete virus scan should be carried out for the entire PC. Most virus scanners allow the scanner to examine the computer in a recurring cycle and to warn you when malware is found.

Trojans are often smuggled in as an authentic-looking email attachment to a phishing email. With this distribution method, the Trojan is camouflaged with an incorrect file name and often with a double ending, e.g.,: “”. If the Trojan is very well programmed, it will even mimic the actual document and install the unwanted program in the background. In that case it would mean, for example, that a media player with a cute cat video would open. In this way, the unwanted program can be installed without the user even realizing it is there. However, Trojans do not always download malware onto the computer. Since a Trojan is any program that installs other programs on the system without informing or asking the user, these can even include useful programs that, for example, help a program run or without which the program would not work at all. Trojans were among the earliest malware programs. They were first mentioned in 1974 in a US Air Force report that looked at various ways to manipulate a computer system. A year later, the first Trojan was discovered, a program called Animal-Pervade. Animal-Pervade was a game where the user was asked to think of an animal and the game tried to guess that animal. If the computer did not prevent it, the game was updated with a new version and secretly copied to other directories on the computer. Trojans quickly became a common way of injecting malware into computers, especially with the rise of social media.

A Trojan (short for “Trojan horse”) is a program that installs other programs, often malware, on the infected computer without permission. The Trojan takes its name from the ancient story of the Trojan Horse, as it is based on the same principle. The city of Troy was considered an impregnable city, and in the end it could only be captured with a trick. So, the attackers built a wooden horse in which to hide. This horse was presented to the Trojans as a gift, which they gladly accepted and brought behind their protective walls. Once the inside the city, the enemy climbed out of the horse and attacked. Trojans today are mostly distributed in the form of freeware such as utilities, games and antivirus programs. Once it infiltrates, the Trojan installs unwanted software that can have many different functions. This includes, for example, spying on the user with spyware or encrypting the device or parts of the device with ransomware.
