What is B-ok.org

B-ok.org (a.k.a. ZLibrary, B-ok.cc) is classified as a browser hijacker that alters your homepage adding an ostensibly better search engine. It stands for the largest ebook library with advanced search options to make the searching process more accurate and faster. Unfortunately, B-ok.org is implicated in shady activity – showing unwanted ads and random redirects during the browsing session. It does not necessarily mean that B-ok.org is a virus, but a browser hijacker that should be removed from your PC to prevent identity threats. This is because such applications can track browser history, passwords, and other data entered along with the usage.

How B-ok.org infected your computer

Hijackers are often distributed through pre-packing techniques. This is also known as “bundling” which has been highly-popular with repacks and other freeware kits downloaded from the web. Downloading software from third-parties pages can enable the risk of being infected with additional programs. Users forget to check “Advanced” or “Custom” sections and let sponsored apps get over the installation line. The way to prevent this logically lies in deselecting such offers inside of these or similar options. Also, you should know that any interaction with shady content like advertisement chains can lead to data leaks or unwanted infections that are being installed in the background mode.
