No IMAPS or POP3S scanning ESET for Mac?? in ESET Cyber Security (for Mac) Posted November 15, 2015 With an increase in malware for the Mac, it's nice to have a little piece of mind. Eset runs quietly in the background and does not perturb performance. I have it on my Mac Mini and, unless I look up at the top icon on my display, I hardly know it's there... As with most anti-virus software, the signature updates are automatic. Also have the PC version on my wife's machine. It's a good product overall.
