Well that's entirely debatable, but Norton AntiVirus is right up there with McAfee im sure. Both McAfee and Norton are big names. I highly doubt your connection problem is security related, try posting in the network forum on this site.
Symantec are crap in my experiance. But Norton is gud and so are alot of the free ones u can download "PANDA" <- uh? Norton IS Symantec :S and Panda screwed up my uncle's computer xD
