Actually, you don't need to enable this particular feature for real-time protection. By default, advanced heuristics are automatically applied when a file is executed and manually scanned. Enabling it for the on-access scan may reduce performance though I have never faced any performance issue.enable advanced heuristics
I‘m testing McAfee now and my position has changed. I would say it has been improved a lot. I'm quite impressed with McAfee's Real Protect technology as it can effectively block never-before-seen threats and roll back the damage they cause. However, Artemis is still prone to producing false positives.ESET for sure, especially when compared to McAfee Consumer Products (McAfee Enterprise Solutions give you more protection against ransomware).
