So, I downloaded Malware Bytes, removed it, and now I can't load sites from my computer without accessing the net. Has anyone else run into this issue?
You can't load sites from your computer without accessing the net? What do you mean by this?
Sites you stored/copied local, or the web? Being not able to access the internet without network-connection would be quite normal imo
If you have trouble to access websites, because your Browser is still messed up with the malware, this could help:

If this does not help you, please reformulate your question, maybe I am just tired, but I don't get what exact problem you have.
To run local-saved websites containing PHP, you need to setup a local Webserver, because PHP is a server-side-script-language. Maybe your Webserver ist offline or needs to be reconfigured? Local HTML files should work without a problem.
If only I could delete this thread...
