We recommend Malwarebytes, on all computers with internet access,

but if you use online banking or use your computer for work, you really should go Premium.

Traditional antivirus relies on outdated signature-based technology that addresses threats at the execution stage of the attack chain. It’s reactive, one-dimensional, and apparently isn’t effective. Malwarebytes employs several proprietary technologies that work together to break the attack chain, from pre-delivery to post-execution.
