So this would be a better option, for a MBP, than the free versions of avast & malwarebytes?DetectX Swift.app is all you need. You can read up on it and download it from here.
There are no active or live viruses in the wild that can infect a Mac, however, there is Malware. Which is why we recommend DetectX Swift.
However, if your school or job requires you to have an AV app installed, let us know and we will recommend one that is not resource intrusive.
