ALL AV programs generate false positives from time to time, which is better than a false negative by any measure.
McAfee wasn’t always my first choice for AV programs but over 8 years has risen to the top due to simple effectiveness.
If you have limited RAM resources it can be slow, though it’s hardly bigger than many of the advertised “fast” AVs like NOD32.
I travel some places even the best of you would crap your pants in, using a variety of ways to protect my OS, but McAfee has never failed me whereas every other AV I’ve ever used has had multiple failures and allowed infections to get into my machines. I’m fortunate I’m good enough to prevent major damage most times, but the reformat -> reinstall theme music has been cued a few times as a result, but NEVER on an installation protected by McAfee.
As an example, I once tried to enter a Unix server that WARNED me not to tread unless I knew how to protect myself and had a browser capable of preventing what was about to happen to me. Of course I ignored the warnings and got the profile for my Netscape 7.2 installation deleted by a script on that server as a result.
Those guys were GOOD man, I was so embarrasssed. I was lucky the hacker crowd are generally non-malevalent and ONLY deleted my browser profile, I’m sure they could have done much worse - but my point is, that’s the sort of trouble I tend to get myself into frequently, and yet McAfee has protected me on most of my 12 machines for over 7 years now.
([I]I do run other AV software for testing on a few of my machines, but not on my personal ones.[/I])
I’m of the opinion those who cast doubt on McAfee seriously do not exercise their OSes enough to know whether McAfee is any better or any worse than other AV programs, and tend to just repeat what they’ve heard others say. There is a reason McAfee has remained at or near the top of the AV rankings for the past 7 or 8 years since I first started testing software - IT WORKS, and it works better than any other AV program, for ME.
OPINION POST, not to be taken as the universal truth for everyone.
