You can be infected by visiting a rogue website (^{Internet Explorer} pop-ups). Makers of Trojans and other pests most often target ^{Internet Explorer}, because it contains numerous bugs, some of which improperly handle data (such as HTML or images) by executing it as a legitimate program. Attackers who find such vulnerabilities can then specially create a bit of malformed data so that it contains a valid program to do their bidding. The more features a web browser has (for example ActiveX objects and some older versions of Flash or Java), the higher your risk of having security holes that can be exploited by a Trojan horse.
