I have a new Lenovo desktop, Win 7 Pro, 64 bit, and haven't gone on line yet as there is no antivirus program installed. I've used Norton Antivirus for years, but I was wondering how the Free AVG antivirus program stacks up against Norton? And is it possible to download the AVG program to a Flash Drive on a computer running Windows Vista HP, and then installing it on the new one before going on line and downloading whatever updates were available for AVG? I know it sounds a little back-end-to doing it that way but I'm really paranoid about viruses. Thank you,
