The warning came as the website run by SCO, a company that sells Unix computer software, in effect disappeared from the web under a blizzard of automated attacks from PCs infected by the virus, which first appeared a week ago. The "myDoom-A" version of the virus is reckoned to be the worst to have hit the internet, in terms of the speed of its spread, with millions of PCs worldwide believed to be infected. Such "zombie" machines begin to send out hundreds of copies of the virus every hour to almost any e-mail address in their files. On Sunday they began sending automated queries to SCO's website, an attack that will continue until 12 February. The attack is the web equivalent of ringing the company's doorbell and running away a million times a second, leaving its computers unable to deal with standard requests to view its pages. "You have to wonder about the time limit," said Graham Cluley, senior technology consultant at the antivirus company Sophos. "Someone could go to SCO after the 12th and say, 'If you don't want this to happen again, here are our demands'." Raimund Genes, European president of the security software firm Trend Micro, said: "Such a programme could take out any major website on the internet. It's not terrorism, but it is somebody who is obviously upset with SCO." SCO has earned the enmity of computer users through a lawsuit it has filed against IBM. SCO claims ownership of computer code it says IBM put into the free operating system Linux, and is demanding licence fees and damages of $1bn. Mr. Cluley said: "It might be that whoever is behind this will say to SCO, 'if you don't want the next one to target you, drop the lawsuit'." SCO has offered $250,000(￡140,000) for information leading to the arrest of the person or people who wrote and distributed MyDoom. Nell Barrett, of the security company Information Risk Management, said, "I would give a lot of credence to the idea of gangs using viruses to extort money. It's hard for law enforcement to track them down, because they're using machines owned by innocent people." A second variant of MyDoom will start attacking part of Microsoft's website later today. The antivirus company MessageLabs said it had blocked more than 16 million copies of the virus in transit over the net so far. But millions more will have reached their targets. The onset of a new generation of computer attacks was marked by ______. A．an organization of gangs B．the infection of PCs C．the sale of a software D．a website's vanishing

Since the Hope Project started, our most important work has been to talk to and keep in touch with parents and with persons with a special need, many in deep distress (穷困) through the Hope Project Help line. We try to offer a wide range of supports (advice, mediation, advocacy, networking, professional placement, etc.) and the fruits of our research into issues of health, education, benefits and care. We are national and are contacted from all over Ireland and internationally. Since our establishment, we have been inundated(使应接不暇) with requests for help from parents of children and adults within the Autistic Spectrum(自闭症). We have as a result developed particular expertise in this area. In the area of Autistic Spectrum Disorders(泛自闭症障碍症候群), the Hope Project holds one major conference and several workshops/seminars every year to bring the most up to date and relevant information to this country. We host a SIT therapy facility, summer camps, and integrated kindergarten. We assist parents in forming local support groups, classes and home programs.
