Windows built in antivirus works fine…
That's what I use on Windows. In the past, Microsoft didn't have a good security product, and it was well worth paying for anti-virus software. Not quite so important now, but it does depend on your internet habits. If you're the type who enjoys casually roaming the net, visiting off-colour websites, clicking yes to all and sundry, use the same password for everything and download 'bargain' software, then remember poor hygiene usually results in catching something nasty.
If moderately concerned I'd advise buying a computer magazine to see what's 'best product' at the moment. The effectiveness of antivirus software depends on how technically up-to-date it is, and it's not unusual to find last year's hot product is today's laggard and vice versa. However, all the big names do a reasonable job, and I wouldn't worry too much about which one unless I was a high-risk internet user.
Mac and Linux are much more secure than Windows, and arguably don't require anti-virus at all. I don't know about Android.
