Can you please help me with "Yahoo search" malware not recognized nor removed?

Question

Need help to remove this "Yahoo" malware from my pc. I´ve found and downloaded "Unhackme" exactly to get this off my Windows 10 OS, but the software does not recognize this as malware, and so I cannot remove it. Need kind of help, please (?)
