Win32:malware from known trusted site

Hello Shelly,

Best regards,
Alok.

I purchased a PC game from Amazon and each time I went to install the game, this message appeared: We've moved NancyDrewLastTrain...to your Quarantine because it was infected with Win32:Malware-gen.

I followed all of the Amazon guides for troubleshooting, I've turned off my AVG web protection (turned it right back on when done) and nothing has worked. When I went to my quarantine folder, the only options was to "delete"

According to Amazon their product is fine, so is this a legitimate threat? If not, how do I get this product installed?

Thank you!
