Win 8.1 Pro 32-bit Right now I have MBAM free edition. Windows defender. Thinking of upgrading to paid MBAM version in order to have real time protection. I have just 5 days ago uninstalled Avast free edition. Qestions : 1. Malwarebytes Premium 2.0 $29.95 Canadian 1 year subscription. 1 license for 3 pcs. Do I have to pay $29.95 each year upon subscription renewal, or do I just re-register ? Renewal once a year itself is too bothersome to me. 2. I also have a link to Malwarebytes Pro 1.7 for non-expiring single license for $24.95. Does this one work just as well as the newer version ? I use it for home use only. Don't need anything too sophisticated.
