The virtual officers, a man and a woman, "will appear either on motorcycles, in a car or on foot, at the bottom of users' computer screens every 30 minutes to remind them of Internet security," the China Daily said.
The two will monitor major news portals and all Web sites and online forums based in Beijing beginning this Saturday.
"They will be on the watch for Web sites that incite secession, promote superstition, gambling and fraud," an official with the Beijing municipal public security bureau was quoted as saying.
The newspaper did not explain how the two officers would monitor sites or enforce laws, but said users could click on the pop-up icons to link to an Internet surveillance center where infractions could be reported.
China already keeps a close watch on the Internet and media and will interrupt signals from the likes of CNN or BBC and black out television screens if a sensitive topic, such as Tibet, Taiwan or media freedom, comes up.
In another clampdown, about 40 online pornographic novels and related Web sites had been blacklisted for "damaging young people's hearts," according to a report in The China Youth Daily, an officially sanctioned newspaper.
"To curb online pornography is the main focus of recent work," the newspaper said, citing the General Administration of Press and Publication.
In April, Chinese President Hu Jintao launched a campaign to rid the country's unruly Internet of "unhealthy" content and make it a platform for Communist Party doctrine.
So far, 128,000 Web pages with pornographic content had been detected and 244 sites closed down, according to the Internet surveillance center of Beijing's municipal public security bureau.
"We have achieved visible results in recent months but there is still a long way to go," Zhao Hongzhi, deputy chief of the center, was quoted as saying.
