Antivirus software causes a lot of problems on every platform. Not the least of which is making everything slow. I've never used antivirus, on my phone or computer.I actually uninstalled the Antivirus App and EVERY issue I had is resolved. Who would have thought.
You are 100% correct. One of the main reasons my Mac runs so much smoother then my PC is the fact that it is not bogged down by anti virus software.
