I have been running ClamXav on my 4 yr old iMac with 4 Gb ram. Based on above comparisons I downloaded and installed Avast, free version. My computer came almost to a standstill. It took 80 seconds to open Safari and another approx 80 to open another site. I checked CPU usage and it was 100%.This was with no scan running. I uninstalled, reinstalled and finally uninstalled after the same results. So, I'm back to ClamXav.
I have a new MacBook Pro and downloaded 'Bitedefender Virus Scanner' from the Apple Apps Store, runs once a day and automatic updates with current software.
What I'd worry more about is the performance hit, and possible software conflicts caused by, deeply embedded anti-virus software running that I don't need.
I have "Malwarebytes for MAC" installed and my MacBook Pro and performs well, when I run it. It is FREE.
Same for Malwarebytes for both WIN pc's + added Webroot.
