Malwarebytes built its reputation as the go-to tool for cleaning up already-infected computers, and it's still excellent at that.

- Strong PUP and adware detection
- Simple, clean interface
- Web filtering included
- Works alongside existing antivirus
Cons
- Higher price per device

- Extremely easy to set up
- Cloud-based management
- Built-in VPN for remote workers
