Ok so my browser has been hijacked. It now launches Discoverreceipt.com search engine every time I open my web browser (I use Firefox). I have no idea why, but this search engine does not work. Of course you understand that i want to remove Discoverreceipt.com hijacker, since there is no point of keeping it on the system… I want to use a different search engine, of course. Please help me to solve this issue..?
