To begin with, the results of your `find` calls will be at least 5 seconds
stale over CIFS share with default settings.
Said that, you could safely write something like
find /xx -type а -iname "zzz" -mtime +10s -execdir 'msg * "Achtung programme crash boom!"'
In regard to antivirus,
1. first make sure your local AV does not scan network directories by default.
This is a gigantic usability issue for multiple reasons and normally is never done.
2. if possible, check what exactly happens when your program loсks up.
Yes, as said above, find will lock /directories/ it is scanning.
This is how Windows filesystem API works.
But it should not lock files by itself.
