There are four main types of spyware. Each uses unique tactics to track you.
- Adware. This type of spyware tracks your browser history and downloads, with the intent of predicting what products or services you’re interested in. The adware will display advertisements for the same or related products or services to entice you to click or make a purchase. Adware is used for marketing purposes and can slow down your computer.
- Trojan. This kind of malicious software disguises itself as legitimate software. For example, Trojans may appear to be a Java or Flash Player update upon download. Trojan malware is controlled by third parties. It can be used to access sensitive information such as Social Security numbers and credit card information.
- Tracking cookies. These track the user’s web activities, such as searches, history, and downloads, for marketing purposes.
- System monitors. This type of spyware can capture just about everything you do on your computer. System monitors can record all keystrokes, emails, chat-room dialogs, websites visited, and programs run. System monitors are often disguised as freeware.
