Keep Emsoisoft, it is an AV, one of the best ones out there, also, it does not sell your data or spam you with adverts to update their product. Use it either with Malwarebytes or OSArmour, either combination will protect you well. OSArmour would be lighter on your rig than MB3. Using too many security programs can slow your computer down and in many cases leave you less protected as they begin to conflict with each other.
Bonus: Malwrebytes and Emsisoft probably have the best customer service in the business.
