Lifetime licenses are not supported. When I installed Malwarebytes 3.0. I got a license for a year. I had all kinds of problems with Malwarebytes 3.0 and I uninstalled it in disgust. I reinstalled Malwarebytes Anti-Malware and Malwarebytes Anti-Exploit. My unlimited license for Malwarebytes Anti-Malware was replaced with one good for 300 days. Neither of the two older programs caused any problems except for Malwarebytes Anti-Malware flagging some legitimate programs as p.u.p. It had removed two good programs. So I reinstalled the two programs. From then on, I would check to see what programs Malwarebytes was flagging and if I wanted to keep them, click ignore forever. Malwarebytes Anti-Malware and Anti-Exploit do not show up in the list of antivirus programs installed on my computer. That means there is absolutely no conflict with my main antivirus program. I think the main reason Malwarebytes 3.0 didn't work for me in that it is intended to be the main line of defense instead of the second line of defense. I think Malwarebytes needs to put out another program that combines the features of Malwarebytes Anti-Malware with that of Malwarebytes Anti-Exploit and still acts as a second line of defense which Malwarebytes 3.0 obviously doesn't.
