I got a tip from a photography friend about this warning. It’s legit! I changed my settings sometime ago so updates are NOT automatic. I must approve all updates.  Read the whole thing!

Update: Another friends emails- ” Yes never run any .exe file from an email.

For updates the best way to click on the help pull down at top left and then click on check for updates.”

Good advice. Thanks WD!
