I downloaded Malwarebytes to get rid of malware that Avast! couldn't, and now I can't connect to a bunch of different sites, including Steam. Avast! had that problem for me at first as well, but all I had to do for that was disable the Web Shield (which was unnecessary anyways AFAIK). Malwarebytes doesn't have that option, and configuring my Firefox preferences has done nothing to fix the issue. I'd just use MacRemover to completely uninstall Malwarebytes, but Malwarebytes blocks that as well.
So here's my question: how can I either completely uninstall Malwarebytes or stop it from blocking sites? By the way, the error is "Unable to connect".
