What is spyware?
Spyware sends information from your
computer to a third party, usually as
part of an advertising-supported
software product. Other terms used to
describe this type of nuisance include
adware, malware, keyloggers, phishing
attacks and snoopware. Each of these
terms has a slightly different meaning,
and in the absence of an official
definition, even lawmakers are
continually reworking the definition of
spyware. Not all adware products are

view pop-up ads.
Some Web sites require that you
install an application before you
use their site or in order to access
their products. Have you ever
visited a Web site and been prompted
to install something? Some sites,
usually ones that offer free
products, use this method to trick
users into downloading spyware.
Spyware makers also exploit security
holes using viruses, fake email
messages, Trojan horses and ActiveX
controls. Using anti-virus software,
ignoring email attachments from
unknown senders and keeping your
computer up to date with the latest
security patches will mitigate this
