Hi, I have been using Mac's forever and I always used an antivirus. I currently use Avast and from time to time scan with MB. I sometime reverse engineer JS and other type of files and they are obviously infected. I move them to VM's to analyze them. I like to have my Mac tell me what happens and then I can whitelist depending on what I want to do. Some websites, very regular, day to day website, I had Avast pop-up for webkit viruses. Anyway, do you use one, which one and your experience on the findings!
