Book Source is a Potentially Unwanted Program (PUP) that also may be responsible for the injection of unwanted advertisements in the user's Web browser. This PUP may be promoted as a great computer program that allows avid readers to find and download thousands of eBooks for free instantly. However, Book Source's capabilities are strongly exaggerated, and this software isn't able to perform many of the actions it claims to be able to. Although Book Source can be downloaded from its official website, the program's authors may rely on software bundling for their product's distribution. By bundling Book Source with legitimate freeware and shareware programs, they can increase the chances that their software will reach the computers of thousands of users across the world significantly.

Once Book Source is installed it may attempt to collect information associated with the Web browser usage, frequently visited websites, search queries, and other information that is meant to be private. According to Book Source's license agreement, the information is non-identifiable, and it may be used for marketing purposes (e.g. advertising). Apart from using misleading distribution techniques and data-mining techniques, Book Source also may display unwanted advertisements in the user's Web browser. The paid ads may be associated with 3rd-party companies and individuals, so there's a risk that they may be used to distribute misleading content or potentially threatening software. Book Source is a PUP that may disturb your Web browsing habits, and that's why its removal is strongly recommended. A good anti-malware utility should be able to remove all of Book Source's components successfully and end this PUP's annoying activities.
