Hello,
Thesearchprivacy.co website became my default search engine. I haven’t made any changes myself; however, I don’t mind using a new search engine, but I searched for information online and found people calling it “Thesearchprivacy.co virus”. So, should I use it or remove it?
The reason why this website became your default search engine is that your computer has been infected with Thesearchprivacy.co. It's a browser hijacker and a bogus search engine; therefore, you should definitely remove it. The easiest way to remove it is to scan computer's system with a powerful malware removal program such as FortectIntego. Additionally, you can eliminate it manually following Thesearchprivacy.co removal instructions.
Sincerely,
2-spyware team.
