I called Nintendo earlier today and told them how I couldn't get online with my DS. Since I had all the requirements needed to get online, the person said that the only thing keeping me from getting me online was the computer's antvirus program which was Norton Antivirus. I checked my computer out and it turns out that if I did delete Norton, I'd be able to get online with Mario Kart. So my question is, Is it worth it? Should I sacrifice the virus protection to get online with my DS? Are there other free Antivirus programs out there? Need some major help here!
