Spyware are programs that automatically download to your computer when you enter an infected website. The files are downloaded in different ways. When you enter a web site that has these types of programs on them they will automatically download to your pc the minute you enter the site. Many times you don’t know they are downloading onto your computer. In order to remove spyware, you will need spyware removal software.
Another way these programs get downloaded to your pc is when you are downloading files or software from a site that has these files. I spent the past 16 years as a systems analyst for a very large company. From this experience I have found that it is helpful to have some sort of spyware removal software on your computer.
It is quite common that many sites that offer free downloads infect your PC with spyware. Once a spyware file is downloaded to your PC it monitors your activity as well as were you go on the web, all your keystrokes, and many other things. The information that the spyware file gathers gets automatically sent off to its host site without your knowledge.
Adware infections are very similar and can slow your computer down...
