I don't see the point. Why would anybody want to activate McAffee anyhow, even if it was entirely free? It's seriously about the most code bloated of all the AV programs available and uses a ton of resources. McAffee is for mainstream users who don't know any better, at least IMO. AVG, Avira and Windows Defender, with up to date definitions and used aside a good malware scanner like Malwarebytes is going to provide better protection while consuming fewer system resources than any of the bloatware versions like McAffee, Norton and Kaspersky. Of course, Kaspersky and Norton are great programs, very effective, but all three use way more resources than is necessary or than other programs with similar effective routines use.
