Start the PC up in safe mode, run a scan, then delete whatever it detects. You may need to go digging manually too- will be in the programmes file but may be embedded elsewhere- download Malwarebytes and that should get rid of the rest of it.

What settings do you normally have your security and privacy at? I keep mine at medium-high with a few custom tweaks and rarely have any issues, havent for a long time. Make sure you download windows defender from the microsoft website if you havent already, nifty tool that lets you decide what runs at start up and what doesnt, alonf with detecting nasty stuff and stopping it from running usually. Crapcleaner is another ultility useful for removing registry entries after the nasties are deleted from the computer..
