Elizabeth. There are initiatives that are attempting to allow emails to be validated, such as DMARC:https://www.globalcyberalliance.org/dmarc/However, not all ISPs, commercial organisations, email hosting services, etc around the globe implement them. They can be problematic to set up, particular where Domain Name entries were set up a while ago when the new protocols weren't envisages, and there's always the possibility an urgent, important email gets rejected. (Although one should normally work on the basis that email is insecure and often unreliable.)Antivirus software isn't effective on most of these emails as they do not contain viruses - they either try to socially engineer people into becoming involved with the sender and sending them money, or take them to links which solicits information from them which is then used to defraud them or to a webpage that does contain malware. There is some software sold to organisations that will vet links in emails and block users from going to them but I'm not aware of this being used in the retail market (although some ISPs could be running it in the background without advertising it).To be honest, I can't see any technical solution is going to be 100% effective, so it's a matter of vigilance and I guess the price of emails being "free"?
