Which antivirus software do you recommend

Now I know there is no such thing as the best anti-virus software, but nevertheless, I’d like to know which antivirus software do you use to protect your Windows PC from security threats, and why you think it is the best! Do you use a free AntiVirus software for Windows; or a paid one? Or do you use a fully integrated Security Suite? Do you have a second layer of defense in terms of an additional anti-ransomware or anti-malware software installed? Please do share below in the comments – which one you recommend and why! Love to hear which antivirus you use! UPDATED ON 30th Nov 2018.
