[What's the biggest development challenge you face?]

For me the biggest difficultly is not being able to afford the art assets for the game, especially 3d models. I can handle most of the coding myself, but I have pretty much zero artistic talent so I have to purchase all the graphics and sound...

[Which antivirus do you use?]

I use Avast and Malwarebytes

[antivirus gt]

Try Malwarebytes, I have used the pro version for a long time, the free version should be able to scan and remove the fake anti-virus though...

[Online email?]

I know that Gmail can retrieve emails from a POP3 account, but I have never tried sending an email with that way. Yahoo has that feature too but last time I checked it was only available in Yahoo Mail Plus (or whatever the paid/premium version is called).
