Downloading tiny_usb_office.zip set off my internet security scanner (up-to-date Norton) so I followed guidelines and scanned it with Jotti and also got several hits:

I do not recall seeing a tiny office usb on this site?
“Be who you are and say what you feel because those who mind don't matter and those who matter don't mind.” Dr. Seuss
Therefore, this is not the place to ask questions about the app.
However, if you go to the app's original site, it does talk about virus scan false positives. If you want to inform Tiny USB Office of your experience, they are the only people that can help you.
I made this half-pony, half-monkey monster to please you.
