For years I have been using Kaspersky and each year when it is time to pay for another years subscription I give one of the other one a go for the free 30 days. I always end up just going back to what I know as I have found Kaspersky it has always just worked for my setup.
@Daniel For the total security it runs about 90 bucks but you get it on 5 devices. However, they usually have some kind of deal that drops it down to abut 50 buck USD. I usually get some kind of email asking me to renew and I get a even cheaper deal than that. So it just depends on when you catch them in terms of deals.
This on my work laptop and Surface. Only thing that annoys me about Avast is the random popups, trying to get you to buy the paid version. Other than that, I've never had any problems with Avast either. As far as free anti-viruses go, I've also used Comodo in the past.
My personal laptop uses BitDefender, whichever paid version my boyfriend subscribed to.
