Really appreciate procedural efficiency mostly

I'm so happy and fully satisfied with Norton. I've tried AVG and Avast before but Norton gives the best performance. Pros: I've been using Norton for my PC and Mac for several years now and it has protected both very well. It's very easy to use and customize (i.e. adding some programs to Exception List or Firewall). It detects which programs are a threat and quarantines them immediately. You'll get a notification once that happens and you can make adjustments if needed (if it was detected incorrectly). Their licensing is also cross platform which is a big factor for me. The license can be used on both computers and mobile. Cons: Nothing to dislike from this software. I've been using it for years and I will never look for anything else. Price and quality of service is perfect for my needs.

Free and has a ton of features like blocking viruses even in the web
