Websearch.wisesearch.info is a browser hijacker. What is a browser hijacker, by the way? This is a special program which invades your PC and tunes up your browser by integrating itself with it. As a result, some particular web-site (not necessarily infected) will appear in each new search tab you open. The same site would come up and serve as a search engine of your browser. This is exactly what websearch.wisesearch.info does with your search settings once it comes into the computer.
