Virus Searches for Pornography The new virus, which is called VBS.Noped.a, searches the target's machine for what it suspects may be child pornography and reports the names of files to the police. There are no reports of police officials acting on such results, and antivirus software companies say it has not yet been distributed widely and is at relatively low risk of damaging computers.

Technically a worm, the virus is of unknown origin and was spotted by computer security companies on May 22. It arrives as an attachment to an e-mail message titled, "FWD: Help us ALL to END ILLEGAL child porn NOW." When a recipient opens the attachment, child pornography statutes appear on screen. The program then searches the user's hard drive for picture files that have pornographic-sounding names and then sends an e-mail message and a list of suspect files to a law enforcement agency picked at random from the program's database.
