Since it was just the internet functions, depending on your internet provider ... it could have just been the all the extra people online yesterday. I know I lost about 5mbps yesterday due to the excess people being online, though it went back up once the fireworks started.
I agree with norton being a memory hog, though they are no where near as bad as they used to be. Still, if you don't have a higher end system norton isn't the best.
Avast is the worst of the free AV's ... I would NOT use it (yes I used to remove viruses for a living)
Of the free ones, Microsoft Security Essentials is the best IME (like Aquaticfan said). Throw on Malwarebytes as a passive scan and stay off high risk websites like Facebook and you should be fine.
For pay ones, Kaspersky is a little better than norton and uses less resources, but it's more hands on ... ie asks for permission for programs far more often than norton does so general users like it less.
