TestiNetSpeed will modify your browser's settings which is why it is categorized as a redirect virus. Browser hijackers generally come along with freeware, and could install without the user even seeing. It's crucial that you are attentive during software installation because if you aren't, you won't be able to block these kinds of infections. This is not a high-level threat but because of its unnecessary behavior, you will want to get rid of it as soon as possible. You'll find that instead of the usual homepage and new tabs, your browser will now load the hijacker's promoted page. Your search engine will also be altered, and it could be able to insert advertisement content among the real results. It would try to reroute you to sponsored web pages so that web page owners can earn revenue from increased traffic. Do take into account that some of those reroutes might lead to contaminated web pages, which may result in a malware contamination. Malicious software is a much more severe infection and it could cause serious harm. If you find the hijacker's provided features beneficial, you need to know that they may be found in reliable add-ons as well, which do not put your OS in danger. Browser redirects are also known to collect certain type of data, like web pages visited, so that more customized adverts may be displayed. Furthermore, suspicious third-parties could be granted access to that info. If you wish to avoid bad consequences, you should immediately remove TestiNetSpeed.
