Who would have thought adorable little Hermione would become the “most dangerous” celebrity to search for online? The 22-year-old British actress, who stars in the upcoming film, “The Perks of Being a Wallflower,” is not a great person to try to look up on the Internet, according to security company McAfee, which claims lots of different sites use photos and information on the celebrity to lead users to download harmful software or provide personal information. One in eight people arrive at a malicious site when searching for the young lady, so the next time you want to know her birth date or what other projects she has in the pipe, be cautious of the Watson-related links you click. IMDB is probably your best bet, if I do say so myself.
