Well, the site isn't all that popular, believe it or not, so it wouldn't be a target for malicious intents. Google is so high because of the fact that it links to sites that have viruses and junk on it. It also hosts advertisements that may have a virus piggybacking on it. Apple is suspicious because it's the site of a big business, and a site that happens to have a lot of traffic every day, so a person who wants to infect a lot of computers in a short amount of time before the site gets flagged and the virus removed would want to put it there.
