Downoading files can include installing programs from a CD, opening pictures or links to Web sites from e-mail, copying Word documents and Excel spreadsheets from the company network, upgrading software acquired from the Web, or transferring music files from a computer half a world away.

Files you download could be just what you expect, but they might also be a vehicle for malevolent intent. Malicious software (also called malware) is software that can harm you or your computer; it can include viruses, worms, spyware, and other unwanted programs.

Before you download files, make sure you are as protected from unwanted software as you can be.

Keep your software safety net up-to-date

• Update Windows automatically. If you use Windows Vista, Windows XP, Windows 2000 Service Pack (SP3) or later, or Windows Millenium Edition (Me), Automatic Updates delivers updates to your computer automatically, so that's the easiest and most reliable way to make sure that you get new security and other high-priority updates as soon as they become available.
  
• Be sure to update your antispyware and antivirus software regularly and then do a scan or schedule one to be done every day.

Improve your computer's overall security

• Lay the protective groundwork. Use a firewall, keep your operating system updated with the latest security updates, and use both antivirus and antispyware programs. Learn more about how to better protect your computer.
  
• Set your antivirus program to scan all incoming files and e-mail attachments before you open them. This is different for every antivirus program, so consult the manual or online Help for instructions.
  
  
• Use a spam filter. Many e-mail programs offer filters that can help block unwanted messages.
  
  
• Install and run a program to help detect and remove spyware. Some Internet Service Providers (ISPs) include antispyware software as part of their service.
