From Paypers:
"Eighteen months prior to the launch of the 2.0 version of its anti-malware software, Malwarebytes began developing two key things: 1) a new product with increased value for subscribers and, in close cooperation with cleverbridge, 2) a successful subscription model strategy. The company decided to rename the acclaimed Malwarebytes Anti-Malware PRO to Malwarebytes Anti-Malware Premium and make it available from its online store for an annual subscription of USD 24.95. Malwarebytes built in added value by extending the subscription’s coverage for up to three PCs. They also offered free upgrades to users with existing lifetime licenses for Malwarebytes Anti-Malware PRO."
