Remove Book Source adware (Virus Removal Guide)

Book Source is an adware program (Rogue.Tech-Support-Scam) that displays fake alerts on your computer that are designed to scare you into calling a remote tech support phone number. These alerts will display fake alerts stating that you need to activate Windows, in an attempt to scare people into calling 1-888-479-3649.
To make matters worse, you will also find that this adware will cause your computer to act more sluggish or for your web browser to freeze.

Unfortunately, some free downloads do not adequately disclose that other software will also be installed and you may find that you have installed Book Source without your knowledge. Most commonly Book Source is bundled within the installers from Cnet, Softonic or other similar custom third-party installers.

You should always pay attention when installing software because often, a software installer includes optional installs, such as this Book Source adware. Be very careful what you agree to install.
Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place.
It goes without saying that you should not install software that you don’t trust.
