What is TopPDFConverterSearch?
The experienced security researchers have determined that TopPDFConverterSearch is a potentially unwanted application (PUA) that falls under the group of Browser hijackers. The aim of browser hijackers is to make advertising revenue. For example, a browser hijacker redirects the user’s homepage to the browser hijacker’s page that contains advertisements or sponsored links; a browser hijacker redirects the user web searches to a link the browser hijacker wants the user to see, rather than to legitimate search provider results. When the user clicks on advertisements in the search results, the developers behind browser hijackers gets paid. The makers of browser hijackers can gather privacy information such as user browsing habits as well as browsing history and sell this information to third parties for marketing purposes.
Most often, browser hijackers promote fake search providers by setting their address as the default search provider. In this case, the TopPDFConverterSearch browser hijacker installs feed.toppdfconvertersearch.com as a search provider. This means that users whose browser is hijacked with the hijacker are forced to visit toppdfconvertersearch.com each time they search in the Internet, open a new window or tab. And since toppdfconvertersearch.com is not a real search provider and does not have the ability to find the information users need, this webpage redirects the user’s web browser to the Yahoo search engine.
As well as unwanted web browser redirects to toppdfconvertersearch.com, TopPDFConverterSearch can gather your Web browsing activity by saving cookie information, web browser version and type, URLs visited, Internet Service Provider (ISP), web-pages visited and IP addresses. Such kind of behavior can lead to serious security problems or user information theft. This is another reason why the browser hijacker that redirects the internet browser to TopPDFConverterSearch should be deleted sooner.
