Anatomy of a malware scam - The evil genius of XP Antivirus 2008
Love the title Jesper!
Jesper's article includes a description of a browser hijack intended to dump its victim at a fraudware site. It also takes a close look at the fraudware itself - its installation, its behavior after install, and how it tries to convince victims to part with their hard earned cash by purchasing the full version of the software.
And, he takes a quick look at its removal using legitimate anti-malware software.
The article is well worth a read.
