How can I know if Book Source has hijacked my computer?

Book Source virus is another rogue program which uses scare tactics to convince people into purchasing products they really do not need. This program is initially promoted as a useful tool for downloading free ebooks. However, good things do not usually come free, so there is a catch to this program as well. In fact, it is an adware-type program, so, as soon as you download Book Source you will notice that it is lacking the promised functionality. What is more, your system may begin to encounter errors; your Internet browser may crash or freeze. All these inconveniences may be caused by the silent, malicious processes this program may be running in the background of your system.

One of the main characteristics of this program is that it belongs to the Rogue.Tech-Support-Scam virus family; therefore, its main goal is to trick people into calling the number indicated in one of this program’s generated ads, and selling them the completely useless support license. The people may be lured into purchasing this license because Book Source ads may display dubious information about the status of your operational system. These ads supposedly claim that the system is not working properly, so the user has to “activate Windows within 1 day to continue using all Windows features.” Under time pressure, people call the provided fake tech support number, which connects them directly to a salesperson, who tries to sell them the mentioned support license. However, we have to warn you not to purchase anything from such suspicious companies.

It should also be mentioned that these ads look very convincing, so you need to be careful not to mistake them with the actual system notifications. A way to check whether the notifications are legitimate is to close your browser or disconnect your computer from the network. If the alerts disappear, this means that you most probably have an adware residing in your computer. However, Book Source has learned how to bypass this verification strategy as well. It installs additional program called box.exe through the help of which it can display the messages directly on your desktop. Therefore, to be safe, it is better not to rush, and scan your system with some reputable anti-malware tool like Reimage, as soon as you see similar notifications appearing on your computer. If the antivirus detects any contents of this virus, make sure you remove Book Source from your computer without hesitation.

How did this virus enter my system?

This virus, like other adware programs may have entered your computer if you have been carelessly downloading and installing new freeware or shareware programs. If you are thinking that staying away from less know and downloading popular programs will save you from the trouble, you may have to think twice. The potentially unwanted programs’ developers target the most frequently downloaded programs in particular. They create software packages in which they bundle a well know program with their malicious creations. The undesirable programs are usually hidden within the advanced installation settings, so it is advisable to always opt for the more detailed installation rather than choosing the “Quick” or “Recommended” installation mode. With the help of the advanced settings you will have more control of your installs and will have a chance to stop the unwanted programs from entering your PC.

How can I remove Book Source from my computer?

There are two strategies that are usually applied in the removal of the potentially unwanted programs. First, the manual removal method. You can, in fact, remove the virus manually, yet it requires some computer knowledge and skill.
