San Diego FBI agents have received multiple calls of a malware virus showing up on their computers with the ability to take valuable financial information.
The Citadel malware is a virus that delivers a type of ransomware named Reveton, according to the Federal Bureau of Investigations.
The malware may cause computers to shut down and then display a warning that the user has violated United States federal law, and that he or she has been identified by the FBI as visiting child porn websites.
Users are then told to pay a fine to the U.S. Department of Justice. The malware also finds users online banking and credit card information, according to the FBI.
"If you have received this or something similar, do not follow payment instructions," read a statement from the FBI. "Infected computers may not operate normally. If your computer is infected, you may need to contact a local computer expert for assistance to remove the malware."
