But UNC officials say the virus, which preys on Kournikova's widespread sex appeal, has caused few problems on campus.
The virus arrives as an e-mail attachment with a subject line "Here you have, ;o)" and contains an attachment named "AnnaKournikova.jpg.vbs."
But when users click on the file, they download a virus instead of a picture of the young Russian tennis player.
Symantec, which specializes in virus-protection software, released a protection program for the virus Monday on its Web site, http://www.sarc.com.
According to the Symantec Web site, the virus is rated a four on a scale from one to five, with five being the most dangerous, because the "AnnaKournikova" virus is difficult to contain and spreads easily.
But Sherry Graham, Academic Technology & Networks director of response services, said the virus was not a large problem on campus, causing less damage than similar viruses like the "I Love You" virus, which hit thousands of computers worldwide last year.
Both viruses spread through e-mail, using the address book in infected computers to send itself to other users.
Graham said it was hard to know how many students had caught the virus. "I've got three infected messages myself," she said. "I just hit the delete key."
Graham said ATN officials have set up a filter on the UNC servers to keep students from getting the infected message -- blocking about 10,000 e-mails.
