They can also take control of your computer and… that’s quite bad. But, fortunately, most Trojans are now stopped by antiviruses.
If we are to compare them to the other types of viruses and worms, there is a little difference: Trojans do not reproduce, they do not infect other files. You can get them through opening e-mail attachments, or some little programs from the Internet that seem harmless at a first glance.
