Avira Free vs Malwarebytes Pro
Hi, I was wondering if Avira free or Malwarebytes Pro is the lightest on CPU and Disk performance. Also, which one has the best Privacy policy.

Kind regards,
I recently tested Malwarebytes pro on my gaming machine and it had an incredibly low background impact, especially CPU. It did have an issue that it wouldn’t stay registered in Windows Security Center. I haven’t tested Avira. Also, last time I checked Malwarebytes had a decent privacy policy and their browser extension is one of the more privacy friendly.
