Your computer is infected with spyware.

Spyware is a program with the main objective of monitoring users activities. But it can also steal private information, install unwanted software, redirect browsers to other websites than the ones the user wants to visit or even displays advertisements.

You are infected with spyware if:

* You see too much pop-up advertisements.

* Your browser has toolbars that you haven't installed.

* Your homepage has changed (and you can't change it back).

* Other settings have changed without your permission.

* Your computer is slow.

To get rid of spyware and keep your computer clean you have to use one antispyware program or even more.
