Some Congress members are asking Facebook to take down pages that appear to be in tribute to victims of the shooting at Sandy Hook Elementary School.
Police have issued a warning about a computer virus linked to a pornographic video on Facebook.
The FBI is getting involved in the investigation and several school districts in Connecticut have issued alerts to students and parents to warn them about the virus.
“I’m very concerned that something like this would be circulating,” said Farmington School District Supt. Kathleen Greider.
According to Simsbury Police Department in Connecticut, the video is shared through Facebook and appears to be from a friend, though it is actually child pornography.
Several Farmington High School students have received the video on their Facebook accounts, police said.
Once opened, the video virus automatically attaches to the user's Facebook account and shares the video with all of his or her Facebook friends.
NBC Connecticut viewers who have received the video say it doesn't appear to be child pornography before opening and contains the phrase "watch this if you're curious."
New Britain police and the New Britain school district posted warnings on their Facebook pages. According to New Britain police, authorities in Farmington, Cromwell and Hartford have contacted the FBI about the video.
Avon schools also sent an email to parents and staff members about the Facebook virus threat.
"Although your child may not attend FHS (Farmington High School), other students or siblings in the area may have Facebook accounts that could be affected and we wanted to alert you of this situation immediately," Gary Mala, Avon superintendent, said in the email. "The video is quite graphic and it will be very disturbing."
Greider emailed every parent and at least three other districts sent out alerts as well.
“We wanted to get a communication out to them immediately,” Greider said.
Facebook has released a statement, saying it has a zero tolerance for child pornography and is aggressively trying to remove it.
The Federal Bureau of Investigation is trying to determine how the images got onto the Internet.
