Using Virus Protection Programs HP provides a virus-scanning software program to help protect your PC (select models only). A PC virus can destroy information on the hard disk drive. You can get a virus from infected files that you open from: • An e-mail message or attachment. • A file downloaded from the Internet. • A diskette (floppy disk). • A CD or DVD disc. Some viruses affect your PC immediately, while others may activate only if you open a certain file or do not delete the file before a certain date. New types of viruses are invented all the time. The virus-scanning software program on your PC has pre-set options that make your PC safe. After you enable the virus-scanning program, it checks your PC files for viruses. The virus-scanning program manufacturer provides free virus definition updates through your Internet connection for an initial period after your PC purchase. You can purchase a subscription service for updates after the initial free period expires. You should take the following precautions to protect your PC: • Do not open unsolicited e-mail from unknown sources. • Download files only from sources you feel are safe. • Always scan documents for viruses before opening them. • Make sure you have the latest version of your virus-scanning software.
