Does this update pertain at all to the actual Malwarebytes program? Does it infiltrate the update process and infect computers when they update?

Or is the only concern the spam emails and the hurt that they are trying to do to Malwarebytes?

It's so sad that this is happening I hope it stops soon and I will definitely spread the word about Malwarebytes!! I have already recommended it to and installed it on the computers of a few friends.
