Text 1 　　At an office in Hampton, Virginia, in the east of the United States, a team of ten net savvy workers scours the web for sexual content, from basic sex education to sex acts. This “quality assurance” team is making sure that the blocking component of Symantec’s Norton Internet Security 2000 computer program remains effective. This is because there is widespread parental concern about blocking websites with sexual content from children. 　　Website blocking is nothing new—services like Net Nanny and programs like Cyber Patrol and Guard Dog have been around for a few years now, protecting children and reassuring parents that only wholesome websites are accessed by the youngsters. Net Nanny and Cyber Patrol will prevent access to any questionable sites when the program is in place. 　　Now Symantec says it has created a new category in consumer software with a package that combines website blocking with a “firewall”, protecting your computer from hackers and viruses, as well as preventing careless disclosure of personal data. 　　In short, Norton Internet Security, as the program is called, is designed to serve as the guardian of your digital health, keeping the bad things out and the private things in. 　　The Symantec program can be configured in many ways: the website blocking, for example, can be set to be either selectively permissive or total in its banning of websites, or switched off entirely. Also, Symantec’s list of no-go areas, which on the CD now stand at around 36,000 addressed, is not confined to sex sites. The team in Virginia is also on the lookout for sites advocating drugs, or which contain references to violence or gambling, and keeps a watch on chat rooms, email services, entertainment portals—even job search and financial pages. These sites can be blocked by the program. 　　Computer users can also refresh the address list online with the Live update feature which is used by Norton Anti-Virus(which is bundled with NIS) to load the latest virus definitions. This service is free for the first year but, including virus definition updates; it costs $19.95 a year thereafter. 　　The system is not perfect, however. Limited testing found the blocking of some “questionable” sites was not comprehensive. Trying to get access to a well-known US site such as Playboy results in an immediate blocking message with a standard invitation to report an “incorrectly categorized” site. By contrast, you could find in other countries such as New Zealand a sex site which declared itself to be “dedicated to providing sexual material, imaged, and anything a little bit unusual for sex enthusiasts all over the country.”
