A few days in, I decided to remove the software and give another product a try. it was buggy and slowed down my system (noticeably). As it turned out, the Mac version of their AntiVirus software was different than the Windows version. It's what I used on Windows, and I knew their products well. I decided to use Symantec's AntiVirus offering. Coming from a Windows-dominated world, I felt the need to install good AntiVirus software as quickly as possible.
My first Mac was a PowerBook (I'm aging myself, I realize).
Waiting to install it later (or not at all) is just asking for serious trouble. In fact, the very first thing I do after installing Windows is to install such protection. In a Windows world, I wouldn't think twice about using a computer without AntiVirus protection.
