If I use file-sharing software, how can I keep my computer secure?

Malicious software (malware) such as viruses, worms, and spyware can be spread through file-sharing programs. If you install a file-sharing program, your computer has a higher risk of infection. Also, many programs shared through these networks are infected with malware or are malware in disguise.

The best way to avoid malware via file-sharing programs is to not install or use them to begin with. However, if you do use them, do not install free software that you find when using them. Also, avoid downloading shared files with extensions like .exe, .com, or .bat.

Note: The University Information Security Office (UISO) recommends that you run the latest version of Symantec/Norton AntiVirus software (available to IU students, faculty, and staff for free via IUware) for your operating system, being sure to upgrade safely (see In Windows, how do I safely upgrade to the latest Symantec Endpoint or AntiVirus software?) and to update your virus definitions daily and scan your computer weekly.
