Safari homepage suddenly changed to localhost

[montanapratt]

Hi there, I'm new here and looking for some help (I'm not sure if this is the right place, so if it's not please point me where I need to go). The homepage on my Safari has suddenly changed to http://localhost/?"\ and I'm unable to change it back to Google. I'm running macOS High Sierra 10.13.6 on a 2016 MacBook Pro. I've removed WeKnow adware (infected via Chrome) from the same computer months ago but have no other symptoms other than the homepage issue now. I 've had Malwarebytes installed/updated for years now and it's returning zero threats. I only updated my OS three days ago so I'm not sure if it's just an update glitch, but the issue only began appearing today.
