Using Windows Defender
Windows Defender is antispyware software that's included with
Windows and runs automatically when it's turned on. Using antispyware
software can help protect your computer against spyware and other
potentially unwanted software. Spyware can be installed on your computer
without your knowledge any time you connect to the Internet, and it can
infect your computer when you install some programs using a CD, DVD, or
other removable media. Spyware can also be programmed to run at
unexpected times, not just when it's installed.
Windows Defender offers two ways to help keep spyware from infecting your computer:
-
Real-time protection. Windows Defender alerts you when spyware attempts to install itself or to run on your computer. It also alerts you when programs attempt to change important Windows settings.
-
Scanning options. You can use Windows Defender to scan for spyware that might be installed on your computer, to schedule scans on a regular basis, and to automatically remove anything that's detected during a scan.
When you use Windows Defender, it's important to have up-to-date definitions.
Definitions are files that act like an ever-growing encyclopedia of
potential software threats. Windows Defender uses definitions to alert
you to potential risks if it determines that software detected is
spyware or other potentially unwanted software. To help keep your
definitions up to date, Windows Defender works with Windows Update to
automatically install new definitions as they're released.

Open Windows Defender by clicking the Start button
. In the search box, type Defender, and then, in the list of results, click Windows Defender.
