How do spyware programs work?

The majority of spyware is installed without the user’s knowledge or permission. Once set up, the spyware keeps an eye on user activity on the Internet and sends that details to another individual or entity. Some spyware trojan (content) programs can track the user’s keystrokes, collect personal info (such as charge card numbers and passwords), and even record discussions.

Some spyware is set up as part of a Trojan horse program or other harmful software. For instance, a user may be fooled into clicking a link that downloads spyware onto their computer. Once installed, the spyware can monitor web surfing activity and even record individual details.

Many anti-virus programs can remove and identify spyware. However, due to the fact that spyware can be set up without the user’s knowledge or permission, it can be hard to discover and eliminate.
