What are the different types of Spyware?
Spyware is a spying software, and as the name indicates, it intrudes into a system and collects information in that system for its host. The spyware developers can collect personal information in the system like bank details, credit card details and observe the person’s online activities.
Spyware can enter your computers without your knowledge by clicking on an unknown link or download from an unauthorised or malicious site. Modern-day Spyware is very sophisticated that varies from harmful trojans to mobile Spyware. Following are the most common classifications of Spyware.
Tracking Cookies:– Cookies are small files that contain your user interface data. When you visit a website, it downloads and stores a text file on your browser that contains your activities on their site, passwords etc. The next time you visit this site, the browser brings back this cookie, and the website can identify it is you. But tracking cookies are slightly different because it moves on from one site to another, observing all your browsing paths. These are mainly used for marketing.
Adware:- Adware or advertisement support software is a kind of Spyware that shows advertisements on your computer based on your searches over the browser.
