Maybe, but then most people wouldn't use any of the Nirsoft tools.
On the other hand - personally - but not because of particular security measures, only for convenience, I tend to run those tools from within the .zip file (opened in 7-zip) i.e. in practice in a "random" directory created on the fly, i.e. something like \7zO6BD1.tmp (inside the users Temp folder).
Besides AFAIK/AFAICR all tools are available in .zip files, I don't think that the "common" user will open the .zip in the "Download" folder and routinely extract its contents in the same "Download" folder (as opposed to a path like C:\Nirsoft\<name of the tool> or similar).
