[Tyson Onaga]"Trying to install (again) and AVG is giving me a virus detection:
I stopped using AVG a long time ago due to too many false positives. It even told me that code that I had just written and compiled was a virus and wouldn't let me run it!!! That's when I uninstalled it and never looked back. I use AVAST now and I'm pretty happy with it, although I spend most of my time on my Mac and only open my PC maybe once a week.
Try a different antivirus software. One that's not so aggressive.
