Right now on my personal Dell XPS 15 I have McAffee. I have a one year license that allows me to install it on as many computers I want.
At the office we are using Sophos but I don't like it at all and many of my colleagues share my opinion. Sophos was preferred by the company because it offers good functionalities for centralized administration. But on my work laptop, from time to time, I feel like uninstalling it immediately.
Another good antivirus is Bitdefender.
