It’s arguably shared responsibility between antivirus software and whatever the heck Square did to their Exe in the latest patch, but this needs a fix, not everyone goes on the forum to check for answers. My solution in the end was to write to D:\FFXIV SCREENSHOTS\ and call it a day, but this definitely broke for me and others with the last patch when it was working fine prior. neither my Windows installation or antivirus software got an update in the meantime, its 100% the game patch.
Typically, some of the AV software works by looking for a change in an existing program or library, then it flags that change as a source of suspicious activity.
The logic behind this is that when a virus 'infects' a program by appending it's code to the programs code, this changes the program very slightly as per what some AV programs use to take a 'snap shot' of the program in it's 'not infected' state.
This generally works fine as a 'good' program doesn't change itself over time, and if it does then maybe there is a virus.
However, as games and other online types of programs get updates and patches, quite regularly, the 'snap shot' state that AV program sees is then different.

This type of AV 'hostility' to updated games and such, is actually a sign of a very poor quality AV program, as it means it is relying more heavily on looking for program changes than actually looking for virus and virus-like code.
The AV program's company needs to address the function by updating it's methodology and definitions, so that a legitimate patched program isn't seen as an infection.
If the AV program has a "Heuristics" based real time functionality, that might be set to a lower sensitivity setting, which would then make it be less freaked out each time FF14 gets a patch, otherwise tell your AV program vendor to fix their poo.
