What is Trojan Horse?
- A program appearing to do useful work but doing harm in the background. A trojan horse is a program that appears to be something safe, but in is performing tasks such as giving access to your computer or sending personal information to other computers
- Trojans are a class of malware that take their name from the way they infect computers. Just like the classical story of the Trojan horse, Trojans hide themselves within seemingly harmless programs or try to trick you into installing them.
- Trojans do not replicate by infecting other files or computers. Instead, Trojans survive by going unnoticed: they may sit quietly in your computer, collecting information or setting up holes in your security, or they may just take over your computer and lock you out.
- One of the most insidious types of Trojan horse is a program that claims to rid the computer of viruses but instead introduces viruses onto your computer.
