If there's a poster child for the dangers of spyware, it's Julie Amero.

The 41-year-old former substitute teacher was convicted of four felony counts of endangering minors last year, stemming from an Oct. 19, 2004, classroom incident where students were exposed to inappropriate images.

Prosecutors had argued that Amero put her students at risk by exposing them to pornography and failing to shield them from the pop-up images after they appeared on her classroom computer.

Amero was an unlikely porn surfer. Four months pregnant at the time, she said she had only just learned to use e-mail. She says she was well-liked by teachers and students at Kelly Middle School in Norwich, Connecticut, where the incident occurred. "I was the cool teacher everybody liked," she remembers.

Amero said she did everything she could to protect her kids, but school officials, reacting to angry calls from parents, went to the police, who soon pressed criminal charges.

The case ruined her life. She believes that stress from the arrest caused her to miscarry her baby, and her career as a teacher is finished. A heart condition landed her in the hospital after she fainted several times. And while she was briefly employed at an area Home Depot last year, she was fired from the job shortly after an employee posted news clippings about her trial in the employee lounge.

Her conviction in January 2007 was the low point of her life, but soon after that Amero found a champion in Alex Eckelberry, the CEO of Sunbelt Software, who contacted her after hearing about her case. After looking at the evidence, he and other security professionals concluded that Amero had been wrongly convicted. Within months they had mustered a high-powered team of lawyers and security experts who ultimately got the guilty verdict overturned, setting the stage for a retrial.

Amero reached a plea bargain agreement with prosecutors late last week. She pleaded guilty to a misdemeanor disorderly conduct charge, paid a US$100 fine and had her state teaching license revoked. Now, she says, she wants some peace, but she's still clearly upset with local prosecutors, whom she says pursued an "incompetent and malicious" case against her.
