Hunting Down Spyware




Spyware is a program that installs itself on your computer
and then without you knowing sends information about the
way you use your computer to some interested third party.
Spyware usually gets installed in the background when
you’re installing another program.
Peer-to-peer music-trading networks (not iTunes, Amazon,
etc.) are one of the biggest sources of spyware.
