Here's a virus total report on the file. I find virus total useful (as a product developer) because it will help show cases where some smaller scanner is reporting a positive.

tl/dr -- virus total is happy with the file.

It remains possible that middleware of some sort has altered the file before you accessed it.

You can check the hash of the file like this:

get-filehash ".\TimeSnapperProSetup.exe"

and it should return "B50A4449C9C36871280A842A530EA19694C7CBC4CF55CED5A620D8838D87CA1E" -- the same hash shown in the virus total report.

Thank you for your quick response! I get the same hash, so a false positive it is. I am really excited to test your product, it seems very nice!
