I am looking for the best Internet security soloution that wont slow your computer down. It's for my Nan's laptop and I will be downloading the gold release of windows 7 to replace the sluggish Vista! She has 1.73 dual core, 1GB of RAM and a 120GB hard drive. Just like my laptop but I only have 1.46ghz. I know that Norton is a system hog! It grinds your system away!
