There's the likely problem, right there on your computer. An overly protective 3rd party antivirus program is my guess. It's probably sniffing inside the ZIP file, finding an EXE that's not commonly downloaded and treating you like you don't know what you're doing. There's no virus in that ZIP or the JetMouse file in it. Some 'nanny-state' AVs are a bit over the top but i understand why that is. Disable your AV and re-enable Windows Defender then try again if you can be bothered.
