keeps hijacking my web browser its called yogo but every time i delete
it it just keeps coming back and the peromance is very poor on my

Hello,

Try this: Right click setup.exe and select Run as Administrator. See if it installs properly this time.

Also, could you post your computer specs here?

Thanks
