Emails

Emails containing a Trojan can masquerade as almost any kind of message, so you need to treat all unsolicited emails with caution. Their main similarity is that they try to get you to click on a link by alarming you (e.g. "your credit card will be charged"), or by tempting you with some dramatic information (e.g. "new sighting of Loch Ness monster" or "someone has sent you a private message"). You should consider using an anti-spam product to help filter out such unsolicited emails.

Websites

A malicious website typically contains computer code that installs a harmful program such as a Trojan or other computer virus onto your computer.

The website may appear to be completely normal, but behind the scenes it will be installing the malicious code on your computer. This will probably not be apparent to you, although sometimes a program will launch unexpectedly, or you may notice a lot of activity on your internet connection as the files are downloaded. The malicious code can be disguised within the page, so will be difficult to spot unless you have specialist knowledge. Even the plainest looking page can conceal malicious code behind the scenes.
