Which American Idol contestant is most likely to infect your computer with a virus?Why it's Taylor Hicks (left), the one who looks like your accountant and is "29". Yeah, we're "29," too.McAfee SiteAdvisor has done research on security and unauthorized AI contestant screensaver downloads and "found that 46% of the top-line search results [carry] hidden dangers."Others Most Likely to Infect: Ace Young (36% of downloads), and Bucky, Kellie and Lisa (27 %). Take heart Melissa McGhee fans - she may have been the first of the final 12 booted, but she won the screensaver safety contest with no unsafe downloads. In Hollywood, that's actually a bad thing.
