Hello I hope someone can help me out please, I purchased a Acer Aspire One net book and need anti virus .... I was given as a gift Norton Internet Security 2010 for my laptop .... probally not the best protection but it was free ....so my question is can I use that on my netbook or do I need special software thats super light for a netbook? The netbook is a basic one 1 gig or ram 250 gb hard drive intel atom blah blah blah ....also since I have three computers that I am able to protect with the Norton am I am able to go to there website and download the software and use my product key since the netbook has not cd drive, any help would be awesome thanks!
