PUP.Optional.PCVARK is Malwarebytes' detection name for a large family of installers for potentially unwanted programs targeting both Windows and Mac systems.
PUP.Optional.PCVARK comes in many forms, but the majority are so-called system optimizers that try to convince users that their system has problems which their software can solve.

Malwarebytes can detect and remove PUP.Optional.PCVARK without further user interaction.
Should users wish to keep this program and exclude it from being detected in future scans, they can add the program to the exclusions list. Here’s how to do it.
