I would dump the MacAfee asap.... I had it on a spare pc that I used as a test rig.
A guy at work gave me a bootleg copy of the companies cad software , I scanned all the software he gave me before I installed it , MacAfee did not find anything but because I am a belt and braces guy I scanned it with antimalware bytes and I am glad I did.
Antimalware found about 10 threats with about 6 segments in each threat. I googled what it found and the threats were keyloggers/spywear/pups. So I have to ask the question , why did the antivirus miss them all because some of them were dangerous items.
For about 10 years I used Norton 360 but 2 years ago I changed to Kaspersky and can recommend it 100% .
NOTE... if you use malware bytes free or premium and the software does detect something you must do repeat scans until it finds nothing , this is because some threats are made up of several segments and from past experience I found that not all discovered segments are deleted on first pass.
