Carelessly downloading e-mail attachments can circumvent even the most vigilant anti-virus software.
Viruses can infect computers without users’ knowledge.
Computer Hacking: Peer-to-Peer networks also have been abused by hackers.
Because these systems potentially expose your computer and files to millions of other users on the network, they also expose your computer to worms and viruses.
To report potential e-scams, please go the Internet Crime Complaint Center and file a report.
Note: The FBI does not send mass e-mails to private citizens about cyber scams, so if you received an e-mail that claims to be from the FBI Director or other top official, it is most likely a scam.
