|Hi, I would suggest Avast Free over Bit Defender:|
Here are some good reasons:
Be sure to use the uninstaller from the norton site:
or else no other AV will work properly.
I would also suggest to cancel your credit card and get a new one re-issued as I KNOW Norton will automatically bill you. It happened to some of my clients and they had a hard time getting the money back.
You do not need the professional Avast, the free one will work great for you.
