So, uh... What's the best antiviruses?

I've heard of Kaspersky, Malwarebytes, bitdefender and this one that all upper case that starts with an E (I forget tbh). I already have safing postmaster, but that isn't exactly antivirus and I don't have the time to go through the full list. Can someone just tell me what are the pros and cons of each of those antiviruses and what they do best?
