     Jonathan James looks like just another kid about to graduate from high school. But

this 19-year-old Swede is anything but ordinary from the computer in his parents' home

he helps the US Federal Bureau of Investigation (FBI) find out the world's most wanted

cybercriminals

     Jonathan first made headlines when he and another Swede, Fredrik Bjoerck, found

out the maker of the " Melissa" virus(病毒)in March 1999. He came to the aid of the

FBI again on May 7,finding out the suspected (嫌疑) sender of the dangerous"I LOVE

YOU" virus. The suspect was caught in Manila on May 8.

Jonathan's special skills are in hot demand as officials around the world express alarm at

the "virtual"crimewave. In between studying for final exams,hanging out with friends and

referring his younger brother's football matches, the quiet, gentle teenager also gives

lessons on e-security(电子安全) to large companies. He reads a lot and exchanges

information with other computer experts to know much about the latest tricks of the

hacker(黑客) trade.

     Many companies have already tried to employ him, but he is not interested at the

moment. Instead, he plans to begin law school in. the autumn at Sweden's Uppsala

University and start up his own security company.

     Although he works with the FBI now and then, his family insists he's just "a regular

kid". Jonathan is a great kid, he has his friends and he does a lot more than just play with

the computer, his little sister Tessa said, adding that he helps the FBI because "He likes

to help" , not because he's looking for fame and recognition.

     When the world was hit by the" Love Bug" virus, Jonathan was too busy preparing a

speech on e-security to look into the problem. "Finally on May 7,I had some free time,

so I 'began looking. " Within a few hours, he had found the suspect and e-mailed his

method and results to the FBI. He said his work on the" Melissa" virus, which took three

weeks to solve was a big help in finding the suspect so quickly.

     "This time I knew exactly where to start. I knew what to disregard and what to look at. "
