I am interested in downloading AirDroid 3 onto my laptop with Windows 10, but, as soon as I start to run the DOWNLOADED programme file, I get the message

 ''AirDroid_Desktop_Client_3.3.4.0.exe
Publisher: 
Unknown publisher '' with a warning ''unsafe to run programme''.

 A similar warning took place when I attempted to run the programme from Google Play, and I felt quite overawed that the warning had come from Google itself. I take these warnings seriously as I feel sure I am downloading the file from trusted sites.
Any comments please.I would scan the file fully with your protection apps...
Once you determine it's clean then you may need to dis-able your A/V apps to install it properly.PATIO - many thanks. Your SUGGESTIONS are very helpful and I will try them right AWAY. Again, many thanks.Rreference: AirDroid is found on Google Play

AirDroid allows you to access and manage your Android phone or tablet from Windows, Mac or the Web, wirelessly, for free. Transfer files between your devices, and share files to your friends. Better focused: Calls, SMS, and the app notifications you allowed, mirrored to the large computer screen you are focusing on.

Geek...i think he already knew what the app was before this...
