FWIW I ran Ninite the other day and it decided I was going to test MalwareBytes 3 :-[.

So far it hasn't crashed, but it does seem to slow down my computer a lot during its automatic scan.

Malwarebytes just released a new version of their anti-malware product, which appears to combine some of their previous products:

With the combination of our Anti-Malware ($24.95), Anti-Exploit ($24.95) and Anti-Ransomware (free, beta) technologies, we will be selling Malwarebytes 3.0 at $39.99 per computer per year, 20% less than our previous products combined and 33% less than an average traditional antivirus. But don’t worry, if you are an existing customer with an active subscription or a lifetime license to Malwarebytes Anti-Malware, you will keep your existing price and get a free upgrade to Malwarebytes 3.0.

From the FAQ in that post, it looks like they will be honoring lifetime licenses (makes me happy, since we have 3 of them running atm :-*).
