I've read the blog click here does this mean if I decide to buy I don't necessarily need Avast anti-virus anymore (Buy the Premium upgraded Malwarebytes, real time as opposed to the Free manual scan version it will revert to after 14 days). The blog, if I understand properly states:
we continue to support compatibility if you choose to use a third-party antivirus or other security software alongside Malwarebytes 3.0.
so it appears to say that it is possible to have 2 antivirus programs running at same time.
I've been lucky by buying 'Lifetime' licences for Malwarebytes before it became a yearly subscription. So I have Pro on four laptops. Since version 3 I've got rid of all AVs except for one. My main laptop and an insider one both run Pro and Defender only. An old single core laptop (insider again) runs with just Malwarebytes. However my daughter's laptop runs Pro and Panda AV. The reason for Panda is it will always ask to scan an external USB drive when it's connected. Her flash drive travels to and from school and between friends.
If I was running Malwarebytes just as a scanner then I would still be running a free AV with it.
rdave13, many thanks, that's very helpful. At the moment I'm running 14 day free trial of Premium Malwarebytes and still running Free Avast. There don't seem to be any problems so will continue with that whilst I decide what to do in 2 weeks time.
I notice that it says 'Ransomeware Protection: On' that is reassuring considering today's news.
