The traditional antivirus programs checked for viruses while files were transferred to disks or downloaded from the Internet. If a file looked suspicious, the program would either delete or quarantine it, thus preventing the spread of malware. The software was good at combating basic viruses, but as malware threats grew rapidly over the last decade, it struggled to identify and stop them.
EDR (Enterprise Endpoint Detection and Response) is also referred to as antivirus replacements, uses an entire set of prevention techniques to stop and identify everything from common malware to novel attacks which have not been seen before. This approach has proven to be more effective than traditional antivirus tools that rely on signature-based detection.

If you're a Mac-user who only uses the app store and maintains a high level of security you may be able to skip the need for one. Every user should consider installing an antivirus program to shield themselves from attack from phishing.
