According to the alert the e-mails tell recipients that their internet use is being monitored by the FBI's Internet Fraud Complaint Center and that they have accessed illegal web sites. The e-mails then direct recipients to open an attachment and answer questions. The attachment contains a virus.
The FBI confirmed that the e-mails, which seem to have an fbi.gov sender domain, do not come from the agency. It stressed that the FBI does not send unsolicited e-mails to the public in this manner.
Recipients of the infected e-mail are asked to report it to the Internet Crime Complaint Center at www.ic3.gov/
