Do you have a restore point from before the problem started? I use Malwarebytes all the time. But it's not infallible. It often marks files bad that may be programs written in a scripting language.
If you can restore to before the problem and get your network back, but still have malware then post the screens from malwarebytes before deleting or quarantining anything.
edit: come to think of it, if your network works then and you have Malware you should probably start a new thread on the Security forum.
