Very slow asset import times on Windows 10!

Since I upgraded to Windows 10, I’ve found converting a project from PC to Android, or Android to iOS to be ridiculously slow.

I’m using an SSD and it took 3-4 minutes to convert my project on Windows 8.1, but now it takes about 30 minutes on Windows 10!

This is when importing any asset from the Asset store, or just converting a project to another platform.

Any ideas on how I can fix this?

I figured it out, AVG Internet Security was causing the slow down. I added my project folder as an exception and that fixed it.
