Thanks for your reply. I hope this is fixed quickly. The first thing I thought was that it was some form of actual malware or phishing exploit masquerading as a Malwarebytes message. I have my browser fairly well locked down, so I haven't seen anything like this in quite a while. I guess it's tough to block a (previously) trusted a application like this on our systems.
Malwarebytes Premium user here and not happy to see this popup tonight. Please disable it and add and opt-out setting to block any future marketing tests. Until this is patched, does anyone have a hosts file entry, IP block, permission setting or another way to block these without breaking the legitimate Malwarebytes functionality that I paid for?
