Tossing Mamutu on my gaming laptop yet again. For some reason I keep finding myself switching between Mamutu and LnS/Some AV combo. With that being said it brings me to my next question. Is a firewall necessary with Mamutu? Secondly is an AV necessary? Lastly anyone have any tips on hardening Mamutu for the best security while maintaining flexibility and reducing system overhead as this is a gaming laptop?
