The vast majority of people here (including me) seem to simply stick with Windows Defender, which is the anti-virus software that's built into Windows 10. (i.e. there's no need to use any third party product at all).
Android is inherently a far safer system than Windows is (because it employs 'sandboxing', to ensure that any dodgy code within one app can't spread to another). So there's no need to add any security software onto an Android phone.
