Integrating into Internet Explorer, Microsoft Windows Defender is capable of intercepting any communication on which some kind of spyware is trying to send or receive information. Thus, the protection of the user's data is guaranteed.
Without requiring any additional configuration, Microsoft Windows Defender will analyze the entire hard drive in search of spyware every day of the week and depending on the severity of the problem, it will start a specific cleaning method.
As with other software, it's possible to start the scan automatically or configure it so as to have special care with specific folders. Since it receives automatic updates rather frequently, almost all the spyware that may appear will be removed, and if this isn't possible, it will be placed in quarantine until it can be disinfected.
