Hi 3DP people and thank you for your application/utility.
I downloaded and installed version 14.10 - was impressed.
I tried it out and pressed 'update', then received the message related above, from my antivirus software, as it put the file in my virus chest (where it remains).
This note is just to say (in the event Avast is not reporting a 'false positive'); your latest package might be infected.
Cheers, keep well and stay safe,
Rick.
