first Keep Kaspersky it is a very good Antivirus - Malwarebytes and Winpatrol are antimalware programs and are made to work with the antivirus.
I do like the paid Malwarebytes antimalware as it does help add an extra security to the computer
The free version of winpatrol will do just fine and the paid version has more bells and whistles - they do not add to the security but add tools to use on the computer
