Just to clarify, a trojan, by definition, tricks or somehow induces a user to install it. They are named after the story of the Greek Trojan Horse used to gain entrance into the city of Troy during the Trojan wars.
Sorry for taking so long to respond.
It seems to me that "trojan" is a misnomer in the present context.
The Trojan Horse was a drive-by...a one-step affliction, while what's called a trojan is a two-step affliction: First you've got to visit the website hosting it, and then you've got to do something stupid.
All the Trojans had to do was visit the Greek's website, i.e. drag the horse into their city, and their fate was sealed.
I've always found it mind-boggling that they were so incredibly stupid!
