Remove BearShare Search Engine Virus (Search.bearshare.net)

What BearShare Is? 



BearShare is promoted as a useful and substantial tool to download as many songs and videos as possible:



However, it reveals its nature as a browser hijacker when it puts its search engine bar without asking for your permission and makes its obligatory appearance to every page you are attempting to visit. Here’s the screenshot of its odd search helper bar:



Looks familiar? YES! It resembles much the interface with Search.fbdownloader.com, searchnu.com and Imesh redirect virus. Such malicious search bar will usually changes its URL, therefore some people get search.bearshare.net, some get start.bearshare.com, other may get home.bearshare.com, efault.bearshare.com, bearshare.net and other affiliate sites.


What Does BearShare Virus Do?




The moment you download BearShare or other programs that is bundled with it, your DNS (Domain Name System) setting is modified, which lead to a different default homepage and undesired redirection to bearshare.com/net. More queries to its sites, more commands it will receive to further compromise your computer including making a backdoor to your system. That’s why some people get additional redirect destination like ask.com or are forced to get unwanted pop ups.

ATTENTION: do not take it for granted. Browser issue as it appears to be, it has something t do with system security. A backdoor manages to make the target computer subject to more infections and place your machine under the reach of a remote hacker. More things will be downloaded to the system, making the machine overloaded to perform poorly. What’s worse, your information will be recorded and scraped without your knowledge. So hurry up to rescue your machine. Any question will be answer if you live chat with 24/7 online experts here.
