T is for Trojan
In the classical tale of the war between Troy and the Greek coalition the war was won by convincing the people of Troy that a giant wooden horse was a gift to the gods. In reality the horse contained Greek soldiers who emerged under cover of darkness and opened the gates of Troy allowing the whole Greek army to easily overcome and destroy the city. Ever since, the term ‘Trojan Horse’ has stood for placing a subversive group inside an enemy’s country ready to recruit and lead fifth columnists.
In computing, the term ‘Trojan’ relates to malware that disguises itself as something beneficial or entertaining, such as a screen-saver, game or even a music mp3 file. Whereas, in itself, it may not perform anything malicious it can ‘open the gates’ for malware to get on to the PC. as most ‘Trojans’ are downloaders i.e. they download other more harmful software on to the PC such as Spyware, worms and rootkits. Because they are installed and operate without the knowledge of the PC user Trojans are also commonly identified as Spyware.
A good spyware removal product such as Spyware Doctor is an essential and effective means of defence against Trojans on your PC.
