I am concerned about security since finding a Mandarin entry in my Apple Calendar! I would like to install BT's McAfee Antivirus for iMac for added protection. My concern is that it will preferentially use my solid state fusion drive capacity reducing the speed of other processes. Should I be concerned?
iMac with Retina 5K display, OS X El Capitan (10.11.6), 2.12 TB Fusion Drive
NEVER EVER install any antivirus, cleaning or any other type of third party maintenance app to Mac OS. If you keep Mac OS up-to-date that is all that is needed. In most cases if you do this Mac OS will run reliably for years.
These forums are riddled with posts from users that have installed some type of AV app thinking they are doing a good thing, in almost all cases the apps installed create many more problems than they solve.
The answer is yes, it will generally affect your Mac, slowing it down is just one of its bad effects. And it will do nothing positive to make up for the bad.
MacAfee is on of the worst choices (Norton probably the worst)!
These are apps developed by PC houses that are really clueless
as to how MacOS (or any Unix for that matter) works. As a result,
they end up creating more harm than any possible thing the "protect"
you from.
FWIW, is your Apple calendar linked to any other calendars, such as
Google, Microsoft or some other online account? If so, those are
the likely culprits. If it is online, it can be altered by anyone who could
hack into one of those systems, although, putting bogus entries into a
calendar is a really lame hack.
you should concerned of any 3rd party Mac AV solution. The forums are writhe with users who tanked OS X trying to protect it using a windows solution when it was the absolute worst thing they could install.
McAfee antivirus for iMac?
