Misconception about Default-search.net


Default-search.net Is Not Virus

As a matter of fact, default-search.net is a browser hijacker, or one can simply take it as a traffic exchanging site since its frequent hijacking is to intercept traffic and re-allocate the traffic to its partners’ sites or the sites made by the same creator. This is the exact reason why anti-virus programs are not able to take down default-search.net.

The industry tends to call default-search.net as PUP (potentially unwanted program) as such items have been found by security companies to be capitalized by infections to execute evil deeds (more information will be provided below).


Default-search.net Is Not Redirector

PC users are simply confused about hijacker and redirector. Strictly speaking, default-search.net is a browser hijacker rather than redirector as it hijacks default homepage, search engine, search results and new tabs. The destination is always default-search.net. While redirector redirects PC users to another URL and just appears for seconds.



Some Features about Default-search.net


Get to know the features about default-search.net will help in understanding the potential dangers brought by the browser hijacker and why such application would be appealing to infections.
  1. Default-search.net bundles with multiple applications and programs: to make itself popular, the browser hijacker would bundle as many programs as possible so that high exposure rate can be achieved.

  2. Default-search.net loads random ads: one could notice the random ads displayed on the interface of the hijacker; with more ads and the corresponding cache loaded onto the target machine, CPU/internal resource will be consumed unreasonably to hinder smooth and normal operation.

  3. Default-search.net, being one of the numerous hijackers, is not necessarily strictly built; thus bug can exist.

  4. Default-search.net is driven by the ultimate goal of getting money within a short period of time. In such case, the hijacker will not filter out partners carefully, some suspicious applications could also be bundled with default-search.net.


Potentially Dangerous Default-search.net


Learning from the features, one should have now known that capitalizing default-search.net would be much beneficial. Once default-search.net is attacked by virus, the virus would be able to spreads rapidly, net many PC users at one time, record confidential information by utilizing the basic techniques (BHO and JS techniques ) involved in building the hijacker.

 

Knowledge supplement: BHO and JS techniques are allowed and basic in building web pages. However, some slight modifications would make the two techniques evil without being stopped by anti-virus programs that stop malicious behaviors based on vicious attribute code.
