MalwareBytes is blocking malicious websites- except I'm not online

I'm getting multiple websites being blocked while not being on any browser. They are from WOW64/dllhost.exe and use various ports, all of which seem to start with a number in the 50s, if that helps at all.

I'm pretty much a complete novice at this, but I know enough to be able to follow instructions, at least.

Any help at all is appreciated.
